There is only one truck of the 1987-1991 era at the local pick N pull, and that is a 1991 F350. I did take a look at the steering shaft on one trip, but it looked like the bolt was upside-down where the shaft clamps on to the steering box input shaft. However, the wheels were straight...
I must look at it again next trip, but when I did take a glance at it last time I didn't look like it was going to be easy to remove...
Should be just as straight forward as the 1980-1986 shaft, ya?
