Resurrection – Name That Differential.

Guys

I am making progress on rearranging my car parts. Brought everything back from storage. So I am taking a few moments to play. And let my back recover. Do we know what these are?

Here are three rear ends,

I will give you the first: Dana 44’s.

The second is?

And the real reason I am posting, from my garage,

The third (2 photos) is?

Prize for second, I buy you a drink.

Prize for third, I buy you more than one drink.

This differential is from '89 #10

Now the legal. to claim prizes, I pick the bar. Travel expenses not included.

I "REALLY" want that Active Suspension rear end to display with my Active Suspension motor.

Brett,

My first thought was to send you an email, but my curiosity asked “what is it.” The second photo is the underside of an active suspension car I took several years ago. Someone from GM was retiring and two of the cars showed up at a hot rod shop out here in SoCal. Later the rumor came to me that the cars had been repatriated back to GM. I would guess that one of these was auctioned off a few years ago just before the BK. They were both running cars.

I originally believed the rear end I had was a test part from the active suspension program. And a few days ago, I compared the photos taken to the part in the garage. They are not the same rear end.

I think what I have in hand was in preparation for one of GM’s dreams. In anticipation of higher output motors, engineers adapted a Dina 60 to run in a Vette. Dana 60’s were used in 4-wheel drive one ton Chevy trucks of the time and were also used in racing.

Back to the activate suspension car, that was one awesome drivetrain. The pump was out of an aircraft hydraulic system. Everything about it looked like it was twice the size that it needed to be. And the technology was well ahead of its time. Problem (as I have heard) is that the computer could not keep up with the car. But that the problem could be beat so it was almost released for production. The price would have been an additional $20,000 on top of the $20,000 for the LT-5. The total cost of the car put it at a price point that was simpily too high to sell at. There would and is still nothing like it the planet.

Looking at the Vette suspension 20 years later with the active damping magnetic shocks, the math is basically the same. The engineers simply moved computer control to the damping portion of the dynamic equation.

Cool piece, George. Looks like I might have saved some money. LOL

California Street Rods.

I bought the stuff from a wrecking yard. I remember at the time a few people posted that there was some unusual Z stuff on Ebay. I knew what is was off the bat when I saw the photos. Car had been crushed.
