66-67 the bottle was nixed from the options list I believe because of the dryer being in the trunk along with the dual MS taking up more room. Also I think the bottle was dropped regardless in 66?

Good point Seth - The 65 rear line was 3/16" and the 66 and later was 1/4". There are a number of Dorman and Edelmann fitting that can be combined to work at the bulkhead for either rear line size. Clark's also sells both front bulkhead "T"'s to accommodate the 3/16" or 1/4" rear line. Inverted flare plugs are installed in the unused ports.

Just FYI. Here is what I did to put a dual Master Brake Cylinder on my 66 Monza. The 68 I dismantled was the 3D sample for my conversion. No kit was needed and really was simple. Only tools needed was a Dremel tool with assorted bits to make "D" shaped holes and double flaring tool for manufacture of lines.

* 68 Master Brake Cylinder from Advance Auto (no Core)
* Pressure switch block and bracket from the 68
* Trunk wall feed-thru fittings from 68
* Manufactured lines using lines from 68
* Obtained lines from blocks to all wheel cylinders from Clarks
* I made a template from the 68 trunk metal to duplicate where the feed-thru fittings holes should be placed in my car.

Oh yes. if you notice, I made my conversion to be like production Corvairs (and Camaros/Novas with manual drums) . CU kits has the fittings opposite to the 68s & later, so spares may be limited down the road.

Mark:

Looks like you are installing yours the simple way like I did. Just like the late production Corvairs. That is the only way to install it, IMO.

I wound up using Summit Racing's dual master on my 66 vert and converted to the 67 bulkhead fittings. Already had the 1/4" rear line but it needs to be shortened to fit. The car has front disc and rear drums so added proportioning valve and 10 psi check valve on rear. I really liked the looks of this master...

What did you use to paint the trunk? Zolatone? Looks great.

Thanks Bob. Now that we know what it Should look like....
Here is a Screen Grab I took from a Youtube video on "What to inspect before buying" a Corvair. Cracked me up to read the caption "Check for...and past repairs". Can YOU spot the past repairs? confused smiley

Why is there a wire going through the same hole as the brake line on the passenger fender?? Someone did NOT want to get Under the Middle of the car to install even the front to rear brake line? eye popping smiley

Great picture! Can't figure out the wire. Side marker lights or lighted wheel wells 😄. Is that the fuel return line on the drivers Side?

I used apollo gray catalyzed Zolotone over SPI gray epoxy.

Great job! Not easy making some of those tight bends by the bulkhead fittings with 1/4" steel line.

I did this last summer. Took the parts from a 68 into my 65. I had to cut/drill a new hole for the second line into the cabin than get those hard lines in place. I used the "L" fitting from the 68 to the rear line and bought a simple reducer to take it from the "L" fitting to the 1/4" line. Lots of fighting and cursing but got it in. The line wanted to hit the clutch lever but after some discussion with the line, it gave up and worked. I think I got the fitting from Summit. I also did a disc brake conversion on the front but that had no effect on the changeover.

E mailed someone instructions and talked with another person today about the lines for these kits. I've sold 200-300 of them at least. If anyone has had a problem with the kits i would appreciate you getting in direct contact with me about them.

99% of the buyers do not seem to have a problem - but then maybe they haven't told me.
