Hi everyone I'm new here but I have a question for you all. My 1977 F-150 is starting to go unfortunately. The floors rusted out and I'm just getting rust in the cab in places I would prefer not to fix. Right now it have the BB 351 in it, 4 speed with granny low, np205, ford 9" rear and Dana 60 front with 4:11's. I found a guy selling a rolling chassis 1986 F-150 and I'm curious if I can put my drivetrain from the 77 in the 86 without too much headache. Mostly concerned about the engine, trans and transfer case. The rears i would like to be able to put in also since idk what this 86 has in it but they are not as crucial. Is this a possible swap or are they different enough where swapping would be a headache?
