So I’m going to do the xB community a solid. Since life has gotten in the way of me making the OEM spoiler install kits, I am going to supply you all with the part numbers so you can source your own.

Parts list is as follow
x2 EPMD rubber well nuts with with brass M6-1.0 insert
x2 M6-1.0x25 Metric yes flange bolts grade 10
Those are for the upper bolts

The lower plastic grommets that the spoiler pins insert to are from a different Toyota vehicle
Toyota Part Part No.: 08150-52867

As for the instruction and templates, I am working on getting those again or you can contact your local Toyota dealership

The lower grommets are about 2mm smaller in outer diameter size which is why when I sold my kits I had to make a correction to the install instructions. Basically find drill bits that will match the outer diameter of the upper well lower part and the outer diameter of the lower grommets. I will see if I still have the specs on that.
