Of the many I have done, the 36 is the least common I have seen. It had been a year since I did a set and could not remember which ones, I referenced that thread and ordered 36mm for my new coupe, and they do not fit correctly between the contacts, causing shorts.
If you get the 30 or 32 and they are a touch too short, they will still work fine because of the size of the contacts, but with the 36, it is difficlut to get them seated without highly modifying the bracket.
Do what you would like, I am simply offering info.
