Bob,

Some of the owners of the 18 that were manufactured banded together to research the known problems and fix them. 16 of the 18 units received those fixes, so those units are capable of being installed and used. Each owner is at a different place in the journey, in terms of being ready to do the installation in a car. For various reasons, it took years to get the transmissions up to snuff so it's natural that it may take some time for the owners to be ready to move forward.

The rights to make more units were sold. That individual is alive and well, so if there is news to share about availability, I'm sure he will.

So... You have seen the pictures of the installation in my car, above. We're working on creating a tunnel cover, since I am using the above-the-floor linkage approach. (I know, it's ironic to add a tunnel to a type of car whose manufacturer prided itself on not having one back in the day.)

As part of that work, we're reconfiguring the back seat, to make room for the rear end of the tunnel and the front cover that was installed over the hole where the transmission protrudes into the car. I have decided to go with a bucket seat approach. I would prefer to adapt an existing seat rather than start from scratch. I noticed that the 2nd generation Camaro ('70 - '81) has rear buckets so am thinking about exploring that direction, especially the seats used near the end of production, since it's my understanding that the amount of frame and springs was reduced, replaced with more of an all-foam design. (Easier to modify.)

I am interested in hearing about other seats that meet these rough criteria:
    [*] Individual bucket seat bottoms
    [*] Primarily made of foam (no springs, not much metal frame)
    [*] Low back, no or removable headrests
    [*] (OK for seat back to be one piece--assume can modify to be two parts)
    [*] no electronics in seat--no motor, etc.
    [*] no or removable manual seat adjuster
    [*] "reasonable" height of the seat bottom (to preserve what headroom there is)

I think you get the idea... Thanks!

It took about 5 years to build the mid engine Jerico transaxle. Alot of misques from other vendors, Do overs and really guessing at what to do next. I hate to think the man hours you guys put into this cause I know what it took to build mine. Good Job!!

Indeed. Thanks for saying that. :-) Have you seen the videos we made of the changes?

Ended up purchasing a pair of Smittybilt #44901 seats. They are intended for a Jeep. Found them locally and it was nice to support a brick-and-mortar small business.

Looks like they will do nicely:



About the same design as the Chrysler front seats. Of course, lots of work to do to actually mount them, and to recover them to match the front seats...

The base sticks out a couple of inches more than the stock Corvair bench seat but that's OK with me. The back seats are going to have very occasional use only.

Looking good! Do those seats fold down like the old bench seat did? Thoughts on how you will fill the gap?

Hi Mark,

No, these seats do not fold. (I believe the seat base is hinged in Jeeps.) Yes, we're working on "filling the gap". The tunnel cover will merge into it. More to show in a few weeks.

Love this thread. Did I see one iteration where the shift linkage was turned back down in the rear seat area with u-joints to get it under the floor?

Another question, would it be possible or practical to use an electric servo shift setup? No clue how but I have seen them on newer cars. No linkage and faster than human hands!thumbs up You probably already considered this.

A bit more progress... Dean fabbed a bracket that uses the existing holes in the floor but scoots the shifter to the center of the car.

I have the under floor setup in my car. I have never seen a servo setup but I imagine you use switches to cause servos to move the shifter to a particular location (gear). The question I would have with that kind of setup would be: what would you calibrate the force to?

That is, I am sure you could tune the servos to the correct location, but the amount of force required to put the car in gear can vary depending on how close the engine and trans speeds are. You clearly don't want to use too much or you will grind gears, too little and it won't shift.

I am sure it could be made to work, it would just take some interesting calibration and custom work setting up the switches and servos.

Depending on how bit the servo setup is you might also run into some space issues. If nothing else you would need to do what Kent is doing and have a split rear seat.

Yeah, I get that. The newer electric shift cars usually have fluid drives so the speeds can be matched by a computer. I could not do what is being done on this thread. The work is amazing. Better than GM by far and as good as any customizer I have seen. The rough-in looks this good, I can hardly wait for the finished product. Really excited to hear/see the initial driving tests. Take video!

Hi Bob,

To clarify, Tim is driving his car (nearly daily). Mine is not yet finished. I will continue to post regularly as progress is made. Probably nothing for a bit with summer vacations and the like.

Has anyone tried to use two cables as were used on Fieros?

Fieros trans were shifted like Corvair with one cable to rotate the shift selector and another to move the shaft in and out.

one thing im almost positive you can do is put more angle on the universals and get the shift tube under the floor board. Some of the rear engine race cars ive seen,Lola,etc have some pretty wild set ups. A high quality universal of course and weve all seen some of the funky steering angles on street rods getting around headers.. Another option that might work is the cable shifter from Renegade (the V8 Porsche conversion shop).
Carlos Arango made a nice console for his floor mounted shifter in his V8 car.
I think this is the coolest corvair mod yet !!! Mike

Kent, very nice work! The the one thing I am surprised you didn't do is adapt one of the nice billet shifters made for a Mustang (or similar) T5. There are so many nice ones that are so much better made than a Corvair shifter. I have often thought of making such a set up since the dimensions are not that far removed from a Corvair shifter but the assemblies are much better made an include positive stops. Some allow bolt on sticks like the old Hurst 4 speed shifters.

Hi Lee,

One thing to keep in mind is that we have to translate the shifting action from the stock T5. The box that you see in the photo I posted earlier has the part that does this, which is a modified version of the part that is in the T5 itself, where the shift forks reside. I don't know what the exact name of it is, but it's the brass part (with shortened steel shaft) seen in this photo I found:



I assume one of these aftermarket shifters could be added to the equation, but it's more than I wanted to get into, at least for now.
