'70 442 - Auto Trans Crossmember Insulators or not ??
I have a '70 442 W30 Auto and recently stripped down the chassis to restore it. The cross member for the auto trans was bolted directly to the side chassis rails (with no insulators).
I've since seen rubber insulators & brackets lists on various parts suppliers sites like The Parts Place (see photo attached), OPGI and others but I can't see anywhere in the Olds Parts Books or Assembly Manual that shows these.
Can anyone verify for me that these were actually original equipment (a photo would be fantastic).
Thanks so much.

I have never seen any type in insulator on any of the cars I have worked on over the years. That's not to say they weren't there from the factory, but I have never seen them and I have had my hands on quite a few since I was 15 (46 now).
My guess would be that they were not used (at least on the 68 and up cars), but that is just an "educated guess" on my part.

A-body Oldsmobiles never used isolators. Other brands did. Yet another case of a mis-informed vendor trying to make more money off of parts that aren't correct for an Olds. Kind of like the repro plastic cowl screens for Chevelles that everyone claims fit an Olds.

I thought that was probably the case when the parts book didn't show them.

Just curious - what would be the harm in using them? I have a new repro pair left over from my prior '72 Skylark that I was planning to install on my '72 CS ragtop when the drivetrain goes back in.

Presumably for the same reason they were used in other A-bodies - to provide a little more road shock insulation for the crossmember. Unless they somehow change the crossmember/transmission mounting geometry in manner not shared with the other A-frames, I wouldn't see any downside for normal driving use.
