I purchased the 900 MM heavy belt from Moss for my 62 TR4. Absolutely no way in hell I can install this belt. I consulted Moss tech rep and he suggested an alternate part that measeres 975M.M. This belt if far too large, there is not enough adjustment on the generator to take up the slack before it hits the inside wheel well. I thought perhaps my generator pully was oversized but according to the rep it is not. I've tried Napa they have the heavy type belt by Gates but cannot seem to fit my application. My next move is going to be shopping the farm equipment parts dealers.I've been down for over a week for lack of a FAN BELT!! Comments, ideas, suggestions anyone?
