Default NEED help with motor mounts

Okay. I'm putting a 98 LS1 into my 1977 trans am. I have the factory mounts from the LS1 but the pedestals that mount to the frame are way too tall. Does anyone have any pics of a similar year model car with a LS1 conversion?

Suggest you look at the BRP site.. they have a kit for 2nd gen F-body...

The Frame mount being cast.. most people don't use them and will switch over to SBC frame mount and Adapter plates for the engine mounts.

For my swap in my 72 bird I just made my own pedestals to use the ls1 mounts. I don't have pics right now but can get some.

I have a 81 in the shop right now, I will mock up with my plates tonight and see if I can't get you pics of what works!

I cut the factory mounts down and welded them to a 1/4" plate. Been using them for years with NO problems...
