A passenger's side bucket will NOT bolt up. The side of each seat nearest the transmission tunnel is lower than the outside portion because it sits on a higher part of the floor. If you put a passenger seat in the driver's side it will be out of wack and even if the holes line up, the seat will be so tilted to the outside you won't be able to close the door.Swank:
You have 60/40 split seats now, right? If I were trying to convert that setup to buckets, I would go the easy route and get a driver's side bucket seat from an S-Runner (what I've got now). It'll bolt right in to replace the 60% wide driver's seat you have. Or, if you're looking to save some coin, a passenger's side bucket from a junkyard Taco will bolt right in. Only problem there is that you'll have to swap out some hardware to put the seatbelt on the proper side so you can buckle up.
Why do all that? The buckles from the Tacoma seat can be bolted to the new ones. I did this with my RSX seats and the bolts for the Tacoma buckles even had the same threading as the holes in the RSX seats.I have Integra buckets in mine. I took my seatbelts out of my taco and had the ends machined down narrower so they will buckle into the integra buckles. Pretty easy to do and they work like a champ. Putting the seats in was easy also, had to drill one hole, and used the rails on the seats so I can still have the sliders.
