My rear frame rails right before the back wheels are rotted out badly, the only frame rails i can find for this spot are from 1987 to 1993 (https://lmr.com/item/LRS-871R/87-93...CFjpv9f_6KxP-BVjcIJU7mU-ziedOgPcaAoGmEALw_wcB) , does anyone know if these rails would fit fine on a 1985, i doubt theres that much of a frame difference, but i just want to make sure.
