What is the white material that you made the pads with. Look really pro! Nice job
I DIY made the square ones from 1" thick x 2.5" wide x (whatever length 1 ft, 2ft, etc) UHMW from mcmaster.
Cut to length with a wood miter saw, hole drilled on a drill press. Surface texture is quite smooth.
Really very easy to work with - go slow - be careful not to let friction heat build up, or expansion might cause blade binding problems.
The round vendor made ones are also 1" thick UHMW, but turned from round stock on a lathe, I suppose. They have fairly deep circular grooves on the surface.
I plan on installing with 150 grit wet-or-dry sandpaper non-slip gaskets between UHMW and underside of body (grit toward UHMW) to avoid slippage & shifting back & forth. UHMW is very slippery - almost as much as teflon.
BTW, all 6 are available from FEBEST - really not concerned about the OEM only thing for this - they 're only body supports, after all, not stressed.
Still costs a lot for the whole set though.
other photos, diagrams, Toyota&FEBEST part numbers here, towards the end.
