Not to argue with you but damn near every YJ I ever encountered, whether is was in the Pine Barrens or the AZ desert had a transplant done on it. I am not talking the guys that bolt a lift kit on and go out messing around, talking the guys that build the things to use them, the guys that twist the wimpy little dana 30/35,s or what ever the hell they had under them into pretzels. The kind of folks that use a winch several times an outing. Not saying they all have transplants, but I have see a ton of them. Just look at the 2 of the companies that offer adapters, Advance and Novak. There is no way they would have been around for as long as they have been if engine swaps were not as popular as they are. Sure both of these companies offer adapters for other vehicles, but last I looked thru the catalogs they were very Jeep oriented.....
