LT1 swap motor mount question
I searched for different motor mount threads here but I didn't find what I was looking for.
I just need to know which motor mount "stands" on the engine side do I need to use for an LT1 swap? I'm using Corvette accessories which is supposedly going to make things a lot easier. I have the rubber mounts that are for a third gen for the k-member side, but I'm not sure which stands or receives if you want to call them that, should I use? Will the 4th gen ones work or do I just need to find a set out of a 3rd gen with a 305/350?
Thanks.

On my LT1 swap and my dads I used the stock 305 mounts that bolt to the engine on the LT1. I had to modify the passenger side one to clear the AC compressor though, but I was using f-body accessories.

You will need to re-use your current ThirdGen "clamshells" too.

Drivers side clamshell is on the Left and Passenger side clamshell is on the Right.
