I apologize already for this question but I have been reading up on seat swaps on here and am stilll confused. I have a 1989 ext cab and am still fuzzy on whats seats are a direct swap and which ones you need to change the tracks on. Someone put newer seats on the truck and they arent a direct fit, but I do not know what year these seats are. Guessing he needed to keep the old tracks. Can some one please clear up the muddy water. attaching a picture of whats seats he swapped in, not my pic but borrowed from ranger boricua's album. Thank in advance.
