an update to answer the question, in short yes. the cab will swap over without any issues except for some minor fab work on the tranny tunnel and creating the proper mounts for the electronics and such under the hood. i ended up giving the truck to my brother after breaking my kneecap twice. i already have 2 working trucks so hes got the parts one and the 87 now. also, its an 87 4wd not 88, my bad.
