'60s axle bumpers similar?

I'm back on my 1966 A-100 and need to source the bumpers located above the axles front and rear.
Are these shared with other models and are they available?
I can supply pics and measurements tomorrow if needed.


EDIT: Removed the huge picture, I'm looking for the rubber parts that go above the axle, on the body, not the snubber.
They are similar to these Chevelle parts.

Looks to me like the rubber you are referring to is the pinion snubber. It looks to be the same as what was used on all the cars through the 60s & 70s. I would think a replacement rubber should be available, Mopar made adjustable snubbers (rubbers with the brackets) for racing purposes. Gene
