i have a 86 runner and ive found a third gen sr5. I was wondering how difficult it would be to put the front seats in my runner. and also if I do the seat swap out of a second or third gen will the passenger seat still slide forward to get in the back like it does now thanks

 

Pretty sure this is covered in the seat swap thread, you should probably read that

anything fits or can be made to, won't slide need to swap out the rails

 

Just use the slides that are in ur truck now and make the new seats fit the old tracks
