Restoration / 1100837 alternator rebuild

« on: March 02, 2020, 10:07:12 PM »

In preparing to rebuild my 37A 1100837 alternator out of my May 1969 Z/28 I find that the rotor hex drive is rounded out. Any suggestions as to finding a replacement? Thanks, Scott

Mild Modifications / Hub Centric Adapters

« on: December 26, 2014, 09:13:30 PM »

I read the earlier thread about mounting Torque Thrust II's on a 67 z/28 but no source for adapters was given. I my case I have a 69 Z with TTII's made in the mid 90's. I've tried the use of conical lug nuts to achieve a better concentric fit and then switch over to the long necked lug nuts but it's quite hard to repeat that successfully. I've contacted numerous Wheel/Tire stores but no one (not even American Racing) offers concentric adapters for my wheels and car. My measurements indicate a 70.5mm ID with a 85.5mm OD and .25inch thick would be good. It seems that I'll have to have custom ones made, but before I do that I thought I'd ask this august body for any other suggestions. BTW, the tires and wheels have been professionally balanced and checked for roundness and that helped but just not enough. Up to 60 mph all is ok, but after that the vibration get's obnoxious. I also tried original YH wheels that when installed work perfectly. Thanks.

Decoding/Numbers / cam ID help

« on: June 08, 2012, 08:01:22 PM »

I'm disassembling a 350 I've had in a bag for about 12 years. The motor has previously been rebuilt but had less than 1000 miles before I got it. The cam is a flat tappet hydraulic. Can anyone identify this cam? Cast into it are "I7  04" "1578 D8" and stamped into the end is "1944 0". There is yellow paint on part of the core diameter. Thanks.

Restoration / Broadcast sheet restoration

« on: March 20, 2012, 08:54:25 PM »

I've decided that I need to get the chassis broadcast sheet restored for my 69 Z/28 before it becomes totally unreadable. I took pictures of it a few years ago but I'd like to get the real document restored. Any recommendations as to who to use? I've spoken to one possible source ACA Paper Restoration in Devon, PA. They claim to have done this a few times and suggested an approximate cost of $250. Thanks much.

General Discussion / Borg Warner T10 identification

« on: December 28, 2010, 08:12:45 PM »

I removed a T10 from my 1969 Z/28 when I bought it years ago and I finally decided to do something with it. Hope someone can help identify what it came in originally. The main case is marked "T10-1B", carries what I'm guessing is a date code of "G20-1" and is stamped "WE82-3" vertically behind the side cover. The input shaft is 10 splines with one groove while the output shaft is 16 splines. The tail shaft is dated 8-24-61. Thanks.

Restoration / wood wheel horn kit install

« on: March 25, 2007, 10:21:49 PM »

Hi all, I'm restoring my 69Z to use a reproduction of the factory wood wheel. The horn kit can be installed several ways but none seems to allow the "down-leg" from the horn cap ring to reach the pin from the kit when I depress the horn cap. I have purchased a GM horn kit and not trimmed the contact pin. So I need some advise/instruction as to the proper sequence and orientation of the T-shaped pin, the coil spring, the plastic retaining sleeve. Thanks.

Originality / head gaskets

« on: October 20, 2006, 06:13:07 PM »

In rebuilding my '69 DZ motor, I would like to know what the original head gasket thickness was. My Chevy dealer recommends an .041 inch compressed composition gasket but something makes me think the original ones were thinner.

Thanks.

I have a build date 5A 69 Z/28 that came out of the LA plant. It came to me with two piece front power disc brake rotors. Any chance these are original to the car?

Thanks
