OOOh, crikey. The gearbox is longer than the 90 box so either the engine sits way forward of the T-Box further back, you might find a RRC front propshaft but the back one might need making (on a 110 try the LSE propshaft :-k)
Rad, well the biggest thing you can fit is a must, perhaps a V8 CSW rad, then you'll need an engine oil cooler and 2 gearbox oil coolers, one to warm the oil and one to cool it. My LSE has a 3rd Kenlowe oil rad under the front end but you could fit one of these instead of the standard cooler. The hot rad or 'heat exchanger' helps the 'box warm up.
I've also heard of filks fitting the oil cooler from a Merc van (pre sprinter type van) on the auto box when towing.
