RE: clutch bell to pinion gear??
What about this one: [link=http://cgi.ebay.ca/OS-MAX-15-CV-R-LIKE-NEW-WITH-RACING-CLUTCH-RS4_W0QQitemZ300100214156QQihZ020QQcategoryZ34063Q QrdZ1QQcmdZViewItem]used OS 15 CV-R[/link]
Be careful as the manifold will need mods to fit the stock RS4-3 and the carb is slider not rotary. It can probably be fitted to replace the T-15.
