A body 4 speed in a truck. Can this be done?

I put an f body 833 of in a 79d100 that started out as a 3 on the tree. I did it because it was what I had and was broke.
I remember going to the junkyard and picking thru a pile of driveshafts and found one the right length, went right in. I don't remember what I did with the shifter as I do remember having to cut the hole anyway. I don't remember if I made a bracket to move the shifter on that one or if I used the location available to me on the tailshaft. I thought I had to make a bracket to move the shifter as there was something about interference with the truck crossmember, this was 30 years ago....
I'm about to swap in an 833 is to an 85 but this time I have a trans that came from an 81 truck going in, should be easier than that 79 was and I don't remember that one being all that bad.
Biggest advantage I have now that I didn't have then is I now have my own 2 post lift, the 79 had to be done on jackstands.
