Hi Guys,
I have a 68 camaro with a turbo 350 crossmember and wanted to know if I got a 700R4 will I need to buy/replace the crossmember?? Or is there a kit/adapter to make it work.

You can slide your crossmember back on the frame, and drill new holes to mount it. I had a TH-400 crossmember modified to fit mine. There are also places like Bowtie overdrives that will sell you a new crossmember.
