I just spoke with 2 service managers at 2 different dealerships and they don't recommend using the new doweled chrome inner primary cover 60792-06C with a engine/tranny case that is not drilled out to accept the dowels. This would just cause more misalignment and eventually chew up the factory IPB and even if I installed a Baker they feel it would eventually chew it up too. The only solution is to either have my black inner primary chromed or for me to find an original 60757-06 which is the chrome version of the one that I have which is black part # 60681-06.
Wow, that's bad news!
I wonder what the dealer does if they need to replace that part? Replace the transmission case too? Or is it still possible to get the original part through Harley?

I asked them that question and they strongly recommend replacing the transmission case too.
I am going to look for an original chrome one that is not drilled but if I have no luck I am going to just go with the chrome inner primary cover and use my original black one and just install the Baker bearing in it.
Hopefully this helps but... regarding the inner primary for an 06 dyna, there are several part numbers that are all the same exact part. Every inner primary regardless of whether its early 06 or late 06-07 is drilled for the 2 locating dowels. The only Harley that doesn't have the transmission case drilled for these 2 dowels is the 2006 Dyna Series. There may be some very late 06's that have the drilled cases because it became standard in 07.
These part numbers include...
60681-06 BLACK
60681-06A BLACK
60757-06 CHROME
60757-06A CHROME
60757-06B CHROME
60757-06C CHROME
60792-06 or 06C CHROME
I called 3 different Harley dealerships and the only part number that is in their system is 60792-06C CHROME
They show nothing in their database for any of the other part numbers even though I have 1 right in front of me with 2 of the part numbers stamped in it from the factory.
A whacky idea:
If the transmission has enough material, I wonder if a junk doweled inner primary could be bolted up, and used as a drill guide to drill the transmission for dowels?
I've never seen the doweled and non-doweled parts side by side though, so I might not have any idea what I'm talking about.
Oh, came across this in a Harley set of instructions for installing a "B" inner primary (two different part numbers) on 06 and up models:
"For 2006 Dyna model motorcycles:
Remove dowel pins from the chrome inner primary housing before attempting installation. Using a pair of pliers or vise-grips, remove the dowel pins by carefully twisting and pulling on the pins.Be careful not to scratch or mar the chrome or sealing surfaces of the chrome inner primary housing."

Its certainly useable. The dealerships really don't know what they are talking about. I know more about this than they do at this point. If you went to the dealership to have a chrome primary put on a 2006 Dyna they would use part 60792-06 and remove the 2 dowels if your tranny wasn't drilled for them. They would then install the stock Harley bearing and sometime after you would have to replace it. If you use the Baker high torque bearing that seems to solve this issue for an extended amount of time. 40K is not unusual. Just to clarify.. EVERY inner primary case for a 2006 Dyna is drilled for those extra 2 dowels. Even the one that came off of my bike (60681-06 Black) is drilled for those dowels. The only thing not drilled is my transmission case. That is obviously a mistake from the factory. Regarding drilling out the case while its on the motor in the bike.... I am looking into seeing if anybody has ever done it. Its certainly something to consider but it would need to be perfectly drilled.
