I think i ordered it off Ebay many years back. I did a quick search and I cant find anything like the unit i have. I think i paid close to 200 and that was well before the past few years insane inflation. Its mostly made of cold rolled. Ive considered redoing the arms that are paralell to the diff bearings with some stronger hot rolled. You can kinda see in the picture the setup is bent from use. Problem is I just set it back in its storage place and will forget about it till the next car. It gets the job done. I could never find alot of great information either about a safe acceptable spread distance. I keep the max travel .008 to .009. I somewhat recall geting .012 or .015 is about the max, but I dont feel like tempting fate.

I kinda hope i did all the math properly. I see most original 4.10 and higher geared GM cars got gear reducers. I managed to find a combination with the main shaft driven gear, and speedo gear that should work without a reducer. Maybe GM didnt have alot of combinations back in the day?

I have one that i got from Randy's Ring & Pinion many years ago when I was a dealer for them. I owned a rear end shop for 15 years and I think I only used the spreader 2 times, and those were aluminum cases. https://www.randysworldwide.com/shop/yt-s01

Holley Carb Restoring
 

Dad and I figured we would try our hand at redoing some holleys for future and current builds.

Dad did the yellow chromating. I will admit its not as distinct as some restored units but for our time and effort we are very happy with the light finish it does have. All the carbs were fully tore down, rebuilt and adjusted. All the smaller pieces were sent off for zinc plating and yellow chromate. Id like to try and perfect the body plating process in the future, but plenty of more restorations to come.

The smaller 4150 is for a 67 SS Chevelle and the larger 4160 is for my current project. There both GM part number and date code correct originals.

I learned alot on this as it was new to me.

L78/L89 375hp 69 Holley
 

69 Carb Pictures, fully restored. I did have to machine provisions in the front bowl for the vent as I pieced this carb together.

Have your door panels arrived? If so, how are they and did they also come from SMS? (No affiliation to my screen name)

I also have a 300 SS Sport Coupe and am stuck with Malibu door panels now.

I have not. I need to give them a call just to make sure they havent forgotten about me. I think the person i spoke with said around a year and I think im now past that by a few months.

Dealt with SMS a couple times, and on my '69 300 post...took about 15 months IIRC for the door panels, but they are sooooo pretty! Got pissed a couple times, no contact by phone, and no email response, but that's how they do business. Sucks, but they are THE best at getting the panels right and using the exact material, either nos or their own duplicate. I've got a set of originals in black, for a post car I'll be selling soon.

Rear End, Axles and Brakes
 

Two steps forward Three back. Once i had the diff in and started doing the brakes i started to notice alot of slop in the clutch packs to the diff carrier. That meant tearing it back out and rebuilding with a set of new clutches and discs. Checked the pinion backlash and shimmed for each side and then reinstalled. First picture is the new carbon clutches. I had never done this before. Pretty straightforward

Rest of the pictures are the brakes, rear end and axles all in. One thing I caught during restoration. The 12 bolt cover bolts were different on the 2 clips and upper larger clip for the brake lines. I can only assume on the line they took out what came from the axle assembly guys, tossed them out and grabbed new ones as the bolt head markings are different. Hope you guys can see that in the picture.

Wiper Motor
 

This was just a simple clean up, replate parts and rebuild. I do wanna throw out there since the 300deluxe had this cheaper wiper motor anyone in the know, let me know if the wiper arm off the motor doesnt look right. I had to do some junkyarding to get the correct one plus the arm assembly that goes in the cowl.
