It can be done but it isn't just a bolt in. The diesel lockup converter is thicker by about 1.5" which means the converter sticks out from the bellhousing face about an inch. You need the 2 nd gen trans adapter and starter. The starter hits the frame rail so clearancing is needed there. The second gen adapter is approx. 1.25 longer to fit the converter so the transmission crossmember needs to move rearwards the same amount and shorten the drive shaft. For all that work you might as well swap to a 47RH and get the overdrive as well. You may need a crossmember from an O/D equipped truck but it doesn't have to be a diesel.
