Yeah, I let them know that I understand mistakes happen and they normally are quick to get me new parts out asap but the fact of the matter is its getting a little old when every single shipment I received has had a mistake the past 3 orders. The sales manager is going to give me a call today to sort it out. Thanks man! Love the look of your 12 BTW. Dialing it in is simply putting a feeler gauge on the back side of the crank and measuring it against the hole in the back side of the bellhousing. This is to ensure that the bellhousing is centered properly on the rear of the engine. Mine was down .010" so I had to order offset dowels, they come in sizes of .007", .014", and .021". Using the .007" will bring me to .003" which is in spec, which is .005". Under normal conditions you probably could get away with being out as far as I was however it puts additional strain on the input shaft and makes shifting at 7K RPM a little more difficult.
