hey hey, wrong forum dude! :p just kidding... sort of.... depending on what transmission you are planning to have back up your powertrain, this swap can be as easy or hard as you want it to be.... personally i would go and find a half-ton 4X4 chevy with a 250-292 in it, that way you have everything you need at a fraction of the cost of just having a bell adaptor made. me, i would hunt for a 4-spd.... even though the 258 is a FAR superior engine..... ;\)
