Ive got a whipple 2.3 going on my 03 with the 3.5 upper, 4lb metco lower and have your 4 piece metco idler kit on order. Need belt size/number info thanks?
We use the website Belt Selection Guide to find out belt sizes. According to that site, it says you need an 83" belt. Hope that helps, let us know if you have any other questions.
