Team, The simplest way to do it is with a Toronado/Eldorado transaxle. A Buick-Olds-Pontiac will bolt right up, with an adapter plate a small/big block Chevy. The internals of the trans.(clutches,shafts,gears) are the same as the TH400, with the front drive parts added. The trans axle & shafts can take SOME abuse. You get an independent rear suspension,4-wheel disc brakes in the deal also. I have seen several of these done over the years. A guy near me built a S-10 with the front motor/transfer case to the front axle & a blown Hemi in the bed with (2) transfer cases, the trans went into one (near the back bumper) up over the rear axle to another one & back to the rear axle. He never did any thing but putt it around at cruises making a bunch of noise, I think I know why. Have Fun, Lorne
