Well, thanks for the push Spiderman and confirm from Rebound. I just ground the nubs off the stock Toyots adapter and tried different mounting positions on the Pioneer deck. I found an immediate alternate spot that was just about 1/2 cm away from the first. I did not think it was enough but tried it anyway and it was enough to get it to fit with the stock bezel (very firm fit) and I will need to add some filler under the deck since there is a little gap but I think that is pretty doable. Had to modify the Toyota side fillers that go with this bezel using a Dremel so it would not hit the rolled edge of the metal adapters. Also had to cut out some material to accommodate a screw that was securing the metal adapters to the HU. I still have more to do but I think I am pretty much in the clear. Will post photos when I have it in place. Thanks again !
