78 and 79 Ford F-150 engines and drive trains

I have 4 total trucks, 3 are 78'sand one 79, these all have been sitting for awhile but 2 are 4 wheel drive. One has been t-boned but still has the original 351 in it and the drive train is still good, the 2nd 4 wheel drive has the original 6 cylinder and both still have the 4 speed granny lo. The 79 has the original 302 and is 2 wheel drive, the last 79 is basically a shell and has no engine but the body isn't bad. Looking to move these so make me an offer
