I am looking to get new rear upper control arm bushings. I ordered 2 from year one but they do not seem to have the ones that are pressed into the rearend? My car is a 66 but the rearend must be from a 64 or 65? Year one says a 66 would take all the same but if they are to be pressed into the rearend itself it must not be a 66? Can anyone help me with this? Also what is the best way to get them out of the rearend and back in without removing the rearend?

if it's a 64 they where used one year only and changed in 65.i used a air chisel and came right out for me.
