Maintenance / Re: M22 Throw-Out Bearing

That link is for a good one.  Has an eccentric collar that prevents rotation of the bearing in the fork. Prevents excess wear on the front bearing retainer snout and the fingers of the fork too.  It will not spin.  Eccentric "bump" needs to be away from fork, not inside fork.

Yes the PS pulley is wrong as it is a standard groove, not a deep groove.  The power steering gearbox has a julian date code stamped on top that might help figure out if it is original to the car.

You are missing part number 3959558 Support Assembly.  It is available in reproduction for about $35.

If you choose to have a better running engine, you may need to select a different cannister.  If you know how much vacuum you are pulling at idle, you can select an optimal canister.

It's about factory "correct" or "better running".  Factory correct is hooked up to a carburetor "ported" nipple.  Better running would not use "ported".  You might need to do some reading on the subject and decide which way you want to go.

I assume Jerry is providing you with a "B28" vacuum canister?  It's a must to getting the manifold vacuum advance working on a 302, or any low vacuum idle application.  Getting hard to find these days.

You need to read this link below.  Your intake manifold needs to be addressed.

The GM Assembly Instruction Manual is great.
GM Service Manual is also great

I am not a fan of Hoopers books. I bought the 67-73 Data book and it has a number of issues.  1 page in the "69 section shows the blue "GM" stickers inside the door jamb that should not be there.  Right next to that photo is a photo of an incorrectly painted (all silver) spare tire rim.  I could go on.  Hard to get it right with a reference like that.

Maintenance / Re: Replacing Heater Control Cables - Maybe

« on: February 13, 2023, 04:38:23 PM »

I "functionaly" rebuilt mine.  Used a common aftermarket choke cable housing. 

Just remove GM control cable assembly from the kick panel and nip off the end of the steel inner cable as close to the jog as possible so you can pull it out of the original plastic housing.  You will be reusing the GM inner steel cable/knob assembly so it looks original once installed. 

Remove the aftermarket inner choke cable from its housing and discard the inner cable/knob.  You will need to measure carefully to set the final length of the replacement cable housing (just a little bit shorter than the original cable housing).  The reason you have to cut it short is because you already trimmed off the original cable so that is shorter now.  Put the original knob/cable into the new housing and duplicate the factory jog bends.  Reinstall the cable assembly.  Works great and looks stock unless you pull the lever out and look very closely where it goes thru the kick panel. Sharp eyes will see the tiny zinc end of the new cable housing only.

Might work for you.

Sorry, but it's a restamp. Trans is too.
Trim tag is an original.

Restamps must be getting better.  This first one would have fooled me for sure.

Decoding/Numbers / Re: Smog Pump Info Help

« on: January 18, 2023, 04:52:24 PM »

Just something to be aware - smog pumps have date codes and a casting number on the rear plate but they are machined differently depending on application.  In other words, you could be holding a Buick smog pump that will not  bolt up to a Chevy bracket.  Dates and casting numbers alone will not positively identify a pump.

« on: January 01, 2023, 02:51:45 PM »

You already have most of the kit so why go that route?  The aftermarket throttle switch, solenoid and switch retainer are all junk.  My advice is to go NOS on the switch and retainer.  Find a used Corvette flapper solenoid (same part number but MUCH cheaper).  You need a few repro parts after that but not too bad. The wiring would be set up to install as an accessory so it's easy.  Even with all that, the setup is finicky.  Mine needs to be messed with every so often to stay functional.  At least it's all there.
