Methinks the Delta 88 Calipers are not GM Metric, at least not the ones I was thinking of. If the picture on the Summit Racing website is accurate (see below), these are not the same style as the GM Metric I used (with Scarebird brackets). The mystery continues
Forum: Corvair Center Forum

The Wilwood website has drawings of their calipers, including their versions of the GM Metric. (The link below is to one of their GM Metric iron caliper datasheet). Compare their pin bolt spacing the brackets you have.

The innerweb led me to believe that the GM Metric caliper is universal design that fits many GM cars. In addition, there seems to be more than a few race car sanctioning bodies that have embedded this caliper into their rules. As a result, the aftermarket for GM Metric calipers is plentiful with varying piston diameters (2.38" is what Corviar needs) and even 2 piston configurations. (

I would get a smooth bolt and new nylon bushing. Having the outside surface slip requires ~2X the torque to rotate for a given fit. I have a nylon bushing also and reamed the I.D. a bit larger with a sand paper "scroll" on a drill. It made the steering effort much more pleasant. It's still an interference fit but I can almost push the bolt in by hand.

This old post has the scarebird instructions and parts list shown. It was very useful when I did my upgrade
Forum: Corvair Center Forum

Last year, I did a front disc brake upgrade using Scarebird brackets and GM Metric (compatible) calipers. I would guess the California Corvair brackets are more of less equivalent. Here is my thread. If you have any questions, fell free to ask away.

I modified the aftermarket brackets for my recaros (for a Nova,I think) to get the rear of the seat to be about 5-6" from the floor. I couldn't go any further without the seat rails digging into the carpet (the front of the seat is much higher.) I'm 5'10" with a 32" inseam (TMI?) and have roughly 4" of headroom now (which is good since the roof is basically a cr

This little tool does a good job of removing wheel studs but is a little tricky for installation (doesn't always end up straight). The HD nut and washer approach described above would be better, I think.

Good thing I didn't place a bet.

If I had to, I'd bet that the A end is the inlet. Walker mufflers use the A/B designation for their non reversible mufflers like this one: Their reversible mufflers seem to be the cherry bomb type.
Forum: Corvair Center Forum

Are you referring to the outlet valve at the fitting for the front circuit? (Way back when, I removed one from a drum/drum MC to make it work with front disc brakes) I can't help with sourcing one but I thought a clarification might further your cause.
Forum: Corvair Center Forum

For what it's worth: In addition, the pipe on the "A" end of the muffler designed to go around a mating pipe, so it would make sense that it would be the inlet of the muffler (better flow)

The 16x7 with 5" backspacing on the front of my LM clear all around. 5.25" would rub on the camber rod at full lock. I am not sure about the rear of an EM. Note: from a purely aesthetics standpoint, with this much BS, the 7" wheels look a little lost in the wheel well. But that's just my opinion
Forum: Corvair Center Forum

For a LM disc/drum conversion with S10 rotors (10.5" diameter), GM Metric calipers (2.38" diameter single piston), and a 1" bore master cylinder, the pedal effort is about the same as drums all around...until the drums fade...at which point the disc setup is way easier

California Corvair sells these parts used at a reasonable price. They vary by year, of course (fitting and tube size, configuration, etc.). They call them "brass tees"
Forum: Corvair Center Forum

At a minimum, the brackets are custom. The rest of the parts can be off the self. Clark's has a 13" kit but no price? All the other kits I've seen on the interweb are for 14" and up. In any case, I'd do my homework to be sure your combo will clear (don't ask me how I know)
Forum: Corvair Center Forum

I did the swap and really like it. It is true that stopping distance has more to do with tires and balance than anything else but drums demand more maintenance to keep them up to snuff compared to discs. The other upside for discs is fade resistance, If you can find aluminum drums for the front, they are a cost effective way to reduce fade.

Her are photos of where the caliper and rim were rubbing (witness marks) and the spacer I used to get clearance. I happened to have this set but probably could get away with a thinner set (I think they are 1/4" thick)

Here's another photo showing the banjo bolt to frame clearance (near spring pocket). The washer under the caliper pin bolt spacer can be seen also. Without it the head of the bolt is about flush with the caliper surface.

Here are photos showing the other end of the bracket and how it interferes with the caliper and how I filed it to fit.
Forum: Corvair Center Forum

Yes, the caliper did rub against the wheel. My photo of the problem is still too big (hard to downsize on my phone). The Wilwood caliper sits proud of the rotor hat/wheel mounting surface and my rims are bulky near the lug nuts. . The rubbing was on the surface of the caliper closest to the wheel centerline (if that makes any sense; wish I could post the photo). I added 1/4" spacers to fix t

If you are just replacing bearings, you most likely can get away with the same shim. This allows you to use not so elegant means to remove the bearing. The link below shows the tools I used to rebuild my differential. The puller I used destroyed the bearing cage so this method won't work if the bearing needs to be saved. Can you send a pic/link to the AutoZone bearing puller you used

If you can spin one rear wheel only (non posi) or both wheels (posi) without the engine turning then that's a good indication it's in neutral.

Update:. Long story short, it was a bad connection. All the troubleshooting pointed to a disconnect between the bulb and the regulator (i.e. somewhere in the brown wire). After disconnecting the engine harness connector to check continuity (which was fine), cleaning the pins and sockets (which didn't look too bad), and reconnecting the harness, I got my GEN light back.
