I lowered the driver’s side seat on mine by replacing the wooden bases with thinner ones. The seat does hit the cover for the leafspring shackles though. One mod I did was to replace the hex head bolts with socket heads as getting sockets/spanners in there was a pain. I then cut the shanks back after fixing as they were sticking out under the car a bit. I also put loops on the seat adjuster bar as the lowering meant jammed fingers against the chassis rail when pulling the seat forward.
The lowering gave a smidgen more legroom under the steering wheel.
didn’t want her side lowered so it is standard fit.
