Seacrhed a few forums & cannot find anything. I have a C4 wayne due with their 6 spd trans mount. Talked with ATS today & they did not know either. My LS1 still has the mounts bolted to the block. I need plates & motor mounts if the stock LSx ones wont work. Anyone?
Scott

just buy the ATS mounts and bolt it to the motor and your all set.
You can't use the stock mounts.

here is a picture of the ATS mounts on my LS2 engine botls right into the Wyne due frame.

Thanks- I called ATS & spoke to Tyler. He said he had no idea if they would work. Glad to finally get a confirmation. What headers are you running?
