Pinion snubber

Hello,

Does anyone have any pictures of what the correct pinion snubber would look like for a 1970 challenger 8.75 rear end?

Thanks

This is the only pic I have of the one for my 1970 Cuda. Has the 8 3/4
Don't have a closer up pic.

Here are some more pics of the shorter style that is correct for E-bodies and others.

Thank you, that looks like the version where the rubber bumper is held in with two metal tabs that get bent over. I think there maybe a version that the rubber bumper has a rubber "tab" pushed through the metal bracket.

As already posted, the rear axle pinion carrier support, or snubber, with the rubber bumper shown, Chrysler number 2403906, is the type originally installed on a 1970 model 8-3/4" rear axle. As noted, the bumper is attached via the integral metal straps to two slots on the support.

The bumper and the support changed in mid 1972 to a push-in bumper and a single large slot on the support. The new bumper, Chrysler number 3643969, was used in car applications from May 1972 - September 9, 1974. This bumper was also used on other rear axles in addition to the 8-3/4" axle. The following image shows the newer style:

The following images show the 3643969 bumper and support with the large single slot:

Part number 3643969 was superseded by Chrysler number 3845139 after September 9, 1974. 3845139 was used in rear wheel drive passenger car applications through 1989 and can interchange with 3643969.

Curious whether there's a taller rubber bumper available.
I have the snubber, but it's so low, I doubt it would ever do anything.

The answer to that lies in a performance part that has been available for many years. An adjustable pinion snubber. Bolts in the same location and is adjustable upwards towards the floor pan. Like this.

You really don't want the rubber up close against the floor pan either. Going over bumps will beat the snot out of your pan!

@Ricks72Chlgr440 I'm missing this button:

You are so right my brother.

I have the pinion snubber shown in your photos above, but I'm missing the two bolts that attach the bracket to the pinion carrier. Can you tell me the following details of the bolts:
1. Size and length of the bolts.
2. Bolt head manufacturer marking.
3. Finish of the bolts (appears to be black phosphate).
4. What is the style of bolt (flanged head, captive washer, or separate loose washer)?
5. What is the diameter and thickness of the washer?
Thanks.
Gary.
