they will use the same bushings as what you see listed.

I just did this with the 85 stepside... I swaped a 91 cab on.


whats is different is the bolts/nuts used.

you do use a few of the old washer with some new ones supplied.

the 85 bolts/nuts(bolts down thru floor-nuts on bottom have a shoulder to butt up on washers and the 91 has a sleeve the washers butt up to with the nut capturd in the floor area. bolts go up from bottom.

on the core support the 85 used a short sleeve in the bushing and the kit comes with 2 sizes so you atch those up.

I can go back and look to see what poly bushing kit part # I used.

they are vage on discription but they do fit 72-93.. just use correct bolt for the yr cab.
