Another PITA to investigate. I ordered upper control arm grommets for my '66 3/4 ton. The old ones were not bad but I figured it's apart, might as well replace as I button it up.

So the replacements do not look nor measure the same as what was on there. Old ones are about 1 1/2" OD, with the hole ID of 1". The new ones have a 2-stage look, about 1 3/8" OD on the large end and the ID at the small end is 3/4".

Is it safe to say I received the wrong part, or is this a later date replacement which has to be stretched into place somehow?
