88 4wd frame with 94 2wd cab Need Help

as the title says i am trying to swap a 94 2wd cab onto an 88 4wd. i got the 88 for free and the 94 was a parts truck for my 1990 thats just a cab now. i also plan to convert the 88 to a 2.4 FI using the parts off the 94 truck. what i would like to know though is if the cab will mount to the 88 4wd without any issues. i know that the tunnels are different so that will need to be fabbed, but is that all? the cab is crunched but the frame is perfect on the 88.

Thanks

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.
