I know we always thought that they were different, based on the Parts List thats been floating around for years, but I've come to learn that its not exactly the most reliable source, and quite out-dated lol.

The Compnine GM catalog lists the same cradle for all years and engines, and car-part.com search also shows the same results for all years and engines.

Engine and trans mounts seem to be interchangeable between the 3 engines, at least for the Monte, Impala mounts have different part numbers, but the brackets and such are the same. Rockauto.com also lists different part numbers for the 3400 Impala engine mounts, while the Montes use the same mounts. I'm fairly sure this is probably just for different mount tuning on the Impala 3400's. Lastly, I ordered a full set of engine/trans mounts from w-bodystore back on black friday, dont think there was any engine specified, and they fit great.

So, are there ANY real differences between the cradles? Or can we put this myth to rest? Laughing

Did some more digging, and they actually did once have separate cradles for the L67, but all the part numbers for all cradles have been superceded (several times actually) and are now a single universal part number.

Might have to call Morad in on this one. Laughing

They made revisions to the aluminum welding process for the aluminum cradle. The early ones were crap. They creaked and moaned and welds came apart. There were numerous TSB's and lousy fixes to those. GM finally learned how to weld aluminum, processes changed, and you now have one cradle for all and one part number. Physically and dimensionally they are all the same. If you want you can even swap in the Pontiac all steel cradle.

I'd imagine that the GP cradle would fit just fine, plenty of GP guys snag the aluminum cradle from our cars to save a few pounds on their GPs.
