You can buy just the center hub.
Part No __ Pulley Face
916663 __ 2.190" comes with Damper #917127E for gear drive, Indy Al timing cover, Jesel belt drive
916661 __ 1.630" comes with Damper #917470E for stock pulley alignment
The only thing I am not sure, is that since 917127E has 3 elastomer rings and 917470E only has 2; will it work with the shorter hub distance?
This is what I was trying to ask the rep at Summit. When I asked if I could just get the proper hub all he said was the right kit for my application is ATI917122E so I am thinking the difference in the dampers’ construction may affect pulley alignment.
Also, I am doing this in preparation to install my BDS 871 blower set up so the stock alignment is critical so that my belt alignment is true.
