You'd have to scratch make the enitre tank. Road wheels and sprockets you could get by with and possibly use the M-41 turret as a base for reconfiguring it, but track & entire chassis are totally different and the back deck is a totally different animal. Many of us have pondered this possibility. Guess we just wait 'til someone decides to make one. Many wishes are now being fulfilled with the new KV and Shermans, so maybe.,,,just maybe..
