Are there any late model aluminum driveshafts that can be picked from a bone yard to use on 60's or 70's Mopar muscle car? It seems that an aluminum junkyard shaft that is too long could be cut down for a lot less than having a new one made so long as the ujoints are correct.

99 to 05 Lincon town car or 99 to 05 Crown Vic is 55 inches long & aluminum. I think some of the larger Rams driveshaft will work also.
