1971 Swinger 318, conversion to a 6cyl/special motor mounts needed

Good luck with that. I am unaware of anyone that makes conversion mounts for what you want. It would be so much simpler to swap to the slant six K frame. Is there any particular reason you want to keep the V-8 K frame?
Basically ,just didn't want to deal with locating a 6 frame then switching it, if I could make the 8 frame work. The left side mounts line up ok, its just the right side thats completely different! At this point I have removed the R mount from the frame using a disc grinder cutter and a saws _all so now just need to get something designed and welded in to accept the engines rubber mount.
