Can someone please help us out. We are putting a built LS3 into a 1978 regal that came with a V6. We already removed the stock FRAME motor mounts. We ordered and installed transdapt kit 4595 but we are confused as to what frame/clamshell mounts we should be using? What are we missing?

Okay so I need to use the stock 350 G body frame clamshell mount. ? What does that red plate come off of or where can I buy them. Those are much wider than what came in the transdapt 4595 kit.

First pic is just the frame pads, with energy suspension inserts in them since the rubber ones were worn.

Second pic shows the 1" set back adapter plates mounted to the block, then to that is the other half of the original SBC mounts (I painted red).

Could look on ebay for some SBC motor mounts, or parts store may sell some. Never looked into it since mine were fine. I would rather have a original set though then some low quality china reproduction crap from local parts store.

Look on gbodyforums and post a wanted ad in the classifieds for some SBC motor mounts.
