I found an 1989 about 600 miles away
Pretty sure that the middle body mount locations changed in certain years, almost certain that an 89 tub won't bolt up to your 77 frame without some mods. If memory serves, 73-77, 78-80, and 81-91 are the years where the frames were slightly different.
Edit: take a look at https://ck5.com/forums/threads/k5-frame-differences-by-year.262940/
If you have the steel cab over the front seats, I don't know how you will get the cage in without cutting something, the cage or the dash, or cut the top off of the cab. Maybe taking the dash structure out is the easiest?? But I don't know what the cage is like, if it will slid in the back to the firewall.
