Completed my three-point seatbelt upgrade. My stock buckle cover was in the process of disintegrating, and since we have a track day at the end of the month...
I got the FJ-40 Toyota Seat Belt kit. It all went together very smoothly... The main challenge was the retractor mounting on the sill, bending the attachment bracket to a precise 20* angle (so the retractor is vertical), and the fiddly upholstery work to my bulkhead cover.
I think it came out pretty nicely.
The lower mount was made more challenging because my car (5357) didn’t come stock with a bulkhead mounted 3-point belt. If that were the case, this would really be a straightforward install.
