Seat swapping options
 

Do seats from a 90-95 4Runner bolt onto the tracks from an 84-89 4Runner?

And are the 90-95 SR5 Bucket seats just as adjustable (lumbar, side support) as the 84-89 SR5 buckets?

Thanks a bunch.

Well they will blot in fine. If you have noticed the rails on your 2nd gen passengers side is shorter, to allow access to the rear seats. The hole for the outside rail is there with a nut plate but there is not a hole or nut plate for the inner rail. (Or vise versa, just doing this off the top of my head) If you use a set of seats out of a 89-95 pickup, the rails are uneven and one side needs a spacer, which sets the whole seat a little high. 4 door 4Runners do not have this issue and work best to swap into a 2nd gen trucks/4Runners.

Some 90-95 4Runner bucket seats are not adjustable but most sr5 have the "sport" adjustable seats.
