I know I found the link somewhere, but I can't remember where. I need the link to the post for modifying the clamshell for the low mount LT1 AC compressor.

 

I found the link with a little more searching. If this link could be added to the frequent QA for LT1 swap that would be great. It also includes notching the subframe, with pictures.

Good stuff but I wouldn't put a bolt through the motor mount that attaches to the back of the compressor like in this pic.

I can see its purpose in that it provides extra support. The reason I wouldn't is because if you ever needed to remove the main accessory bracket for any reason and wanted to the ac compressor to have a little more play while removing stuff if ever needed to. I think the long motor mount bolt would need to be removed then the engine jacked up to get to the bolt that I don't think is needed. Could be wrong though.

 

I understand your point, but that is the cheapest solution I've found so far. The relocation bracket isn't in the budget right now. there is a chance that the bolt can be snuck out.
