I ordered a set of contacts from Roger Brown. Of course, with total disregard for the value of my own time, I actually removed my starter, noted the needed style of contacts, and reassembled and reinstalled the starter. The proper parts came promptly, but because I tightened everything up the starter worked fine (and has been working fine for the past year) I suppose my partly worn contacts were just loose.
I know I have the parts around somewhere, but It would take at least an hour to dig them up.
Don't waste your time like I did, if you are confortable doing this repair yourself, just order one of each (A, B, C & D) for US$19.50 and sell the unused ones back after you do the repair.
I'd just tell you what parts I ordered for my camry, but I can't find the parts. I'll take a photo and make a post if I find them.
