well... got back from boston and had time to install the os 18 cvr into the truck before bed... took less than 30 minutes from start to finish... talk about drop in... only changes were linkage adjustments and longer fuel tubing due to the input nipple having to face the rear because of the header pipe... the clutch and bell fit perfectly and NO shimming was needed... I'm not crazy about the HUGE air cleaner and will get a motorsavor to fit.. will try and fire first tank this evening if no rain... can't wait...
