Thanks "Too Many Projects' .... Yes, all the control arm bushing have recently be replaced (Moog) - and we put two new bushing the housing now going in. Hopefully by Wednesday it will all be installed. I'm really hoping I can take the car to the Pure Stock Muscle Car Races in Michigan in about 2 weeks - wish me luck

I've been working on getting the transmission governor re-calibrated so that the trans will shift where I want it to. Lots of fun playing with 6 weights and 6 springs - there's a million combinations. Looks like in the end it will be some combination of getting the governor calibrated and me making the 2-3 shift. But I'm much happier with the trans now than when it just had the stock shift points.

Well the 3.73 rear end is in the car - and the fluid leak associated the rear pinion seal has been fixed. Seems they sell you a seal for a 12 bolt truck rear end now instead of one for a car - Oh well, it's fixed.
I will load the car today or tomorrow for the trip to the Pure Stock Muscle Car races. Don't know what the car will do but I'm sure I'll have a good time.
I'll let everyone know what the car runs when I get back.
Hope to see you there !!!!

Almost all of the pinion seals that you get now are for the 12 bolt truck rear end. Some of them are deeper than others. I've had to leave some of them sticking out about 1/8 inch on car housings because the rubber seal makes contact with the outer pinion bearing. I believe Ratech sells the correct car seal, but I haven't used it.

Yes - we did all of that. Even tried a different used pinion yoke the second time. Looks like I will have to get a new pinion yoke, and another new seal.
Looking on Ratech's site - they list the same seal for both the car and the truck. They don't list a different seal for the 12 bolt car. I may call them, or email them, and ask about it.

That's still the truck seal.

Are you sure, Fred? I used that one and it fit like the original.

Yes I'm sure. The original car seal did not have the flange on it. It was more of a cup shape, similar to the axle seals.

Thanks, Fred. As for the correct appearance, you are correct.

But, it is not the truck seal. It is a replacement part that works as intended.
