Ed,

That is a tall order. If you are going with 36's and use to driving a Taco i would say go with longest wheelbase possible becase short wheelsbase like a CJ5 can be a handful in climbs and decesnts. Therefore i would say a CJ7 and if you want one that is going to handle a 36'' tire you'd have to look for a 86 they have a 44 rear end. The other CJ7's Have AMC 20 Rear Axles they are a strong axle when converted to 1 piece. The Older CJ's can be found with a t18 4 speed with low first gear. IF you leave the dana 30 front open you maybe able to handle 36's. Thats My .02
