I have seen some mention and pics of these two big rubber pieces that fit on the ends of the crossmember at the frame, for vibration or something. I don't recall seeing these on mine. Any idea what years/models they came on?

 

Buick used them on a lot of applications late 1960's into early 1970's. I'm not sure what application of Oldsmobile used them. John

 

i may be wrong but i think it is mostly a big car item. i just pulled a set from a 66 Ninety Eight for a member here. i am not sure what other years have them.

 

I've seen them on Chevy A-bodies,but not any Oldsmobiles.The crossmember bolts directly to the frame.

 

I am 110% sure the 1964 Jetstar 88 with the heavy-duty frame uses them.

 

Maybe teh Jetstar did,but the Cutlass/442 did not.

 

Pontiac A-body cars used them too. The last time I got a set was in 2008. New GM!

 

I bet the rule of thumb is anything with a heavy-duty frame has them.
