So I picked up a MIP "Heavy" 3 Shoe clutch set, and i'm not convinced it a heavy spring, so I did some research. My "Heavy" clutch kit I got from Amain came with 3 carbon shoes and 1 spring.
When I called MIP they said their Heavy spring kit comes with 2 springs. and their light uses one. Makes sense right. But when I went on MIP's site to double check it shows
Their heavy clutch kit shows using 1 spring. Part # 1633
Thier light clutch kit shows using 2 springs. Part # 1632
On Amain Website website
They list the MIP Heavy clutch, shows the single spring their part # 1633
They list the MIP Light clutch, shows the 2 spring kit and their part # 1634
So bottom line I have checked 3 sources and nothing has matched, MIP's website doesn't even have a 1634 part number and I can't get ahold of anyone that knows what they are talking about.
Any help here.
