Just bought an 87 samurai and already ripped it down to the frame and body. I have an 81 toyota pickup i have ripped apart too and plan to put the toyota motor, tranny, and rears under the samurai. Also plan to 4-link both front and rear and slap some coil-overs under it. The only problem i found i might have is being the transmission is much longer on the toyota, the back drive shaft will have to be considerable cut down. I roughly measured it to be around 30 inches long. I thought about extending the frame so i could lengthen the wheel base but i'd like to keep the stock body on it. think i will run into any problems with the driveshaft being so short?? any ideas?
