Like Frankly says, I don't think a custom radiator is necessary. In my swap I ended up routing twice the length of radiator hoses and just cobbling it all together. Just makes a block heater and full grill block more important with the increased volume of coolant. Exhaust is just about bendin' pipes and welding, don't forsee much problem there. The clutch might be a little beastly, but the shift linkage... that's gonna be the problem I'd love to see what you've got up your sleeve to solve. You may be able to get lucky with a driveshaft... there may be a few different lengths that fit into the G10 transmission splines maybe from different year samurais when there were changes to the wheelbase???(not sure if this happened) maybe from a sidekick? X90? Any other suzuki liable to have RWD? Very tricky stuff. I tried using a pipe sheath initially for one of my axles and it sheared apart during the maiden voyage. If you can't get a stock driveshaft to pop in without modification, that's the part I'd spend the most effort/money in getting right. I'd get two of them made and carry one right in the car with you at all times - this is the part most likely to get you stranded somewhere.
