To get it home... how bad are the tires? Obvious bad dry rot cracks or not? If not, I'd make sure they are aired up to at least 45 PSI, including the spare, and run it.
Most likely the bolt pattern is 8 x 6.5". Check is always a good idea. If the tires are really bad, JY wheels and even tires should fit in a 16" or 16.5" size. Donors can be up to early or mid '90's when the switch was made to metric bolt pattern.
FWIW there is very good selection of 17" aftermarket wheels for 8 x 6.5" bolt pattern in both steel and aluminum. Tires also.
The guy says tires are good.....I've heard that before....the wheels are 17.5 I have NO idea where to find affordable tires in that size which is a shame because the stock wheels and dog dishes look sweet on the truck....I will look to see if I can find some JY spindles and look at a brake swap...I already grabbed a 8 3/4 out of a 67 1/2 ton
