My friend who built the car posted an add on our local board that I wanted to repost as it provides a little more detail.
The setup includes the radiator all the way back to the driveshaft, so it is a complete drop in solution (except I still don't think it's a good clutch/flywheel for the street and would be willing to sell that separate).
He's asking more money than I originally posted since it includes a few more parts, but I'm willing to negotiate
I'm going to post it on BF and ebay but thought I'd update the post here first if someone was looking for an ideal swap.
