I have a set of original mounts for a 430/455 into my '68 Riv but can't remember which part number goes driver side/passenger side. I'll dig them up and post the p/n unless someone can tell me which p/n matches. I've done the searches but find no P/N. I have the Chassis Service Manual but not finding it there either. Thanks.
Any luck with this, Gary? You may just have to do trial and error. If you have them reversed the engine will probably sit crooked. Are you sure they're original? They shouldn't have the interlocking tang. That was after 69 (not sure how far after - my 69 doesn't have it on the driver's side. The aftermarket mounts really make the engine sit crooked in the bay.
Aftermarket Buick mounts?! Where? I'm trying to put a 72 skylark motor into a 85 b-body and don't have any frame mounts.
You can try looking thru this ebay store for mounts. http://stores.ebay.com/id=37275372&ssPageName=STRK:MEFS:MESST
Yardley, Didn't you have side by side pics showing the differences in the left & right mounts at one time? :idea2: I re-used my old driver's side mount this last time and the engine fell right into place. No more cockeyed engine. :TU:
