There is a guy in OKC that has a '55.2 Chevy truck with a 3.8L Jag engine, along with the IFS and the IRS from that same donor car. It's been a year or so since I've seen the owner or the truck; but the last I saw of it, it had the suspension under it. The truck was getting ready for paint. I need to track it down and see if it ever hit the road, or if it's still "under construction".
I've thought seriously about the same thing with either a Pilot House Dodge, or an AD Chevy, but finding a complete body and frame WITH title is proving to be a real job.
