Have 340 swinger and 71 scamp... Do i cut up scamp 4 dart? Or build 340 scamp clone?

well, my real turmoil is not restoring a real 340 car, but letting it rot to nothing. i could see if no title, fender tag, and build sheet were not avail, but i have it all. that is my only gripe with it, and for the 500 i paid for the scamp, it would live on in the dart
