Great, lol.
My guess is the previous owner (who works in my local model shop) fitted an AR28T when he owned it. He gave my an AR28T with the car for me to fit if desired. I could ask him, lol, but not before i want to get it back together !
I just want to make sure that they're aren't beige uprated idlers available as, if there isn't then the one fitted must be the original standard one. Also, my standard Mad Rat has a black idler
