Looking for this extra lenght shaft for my Milodon external oil system.
Not sure if I want to post part numbers, because it seems today, companies use old Mopar PN on standard lenght shaft.
Anyways Old DC# is P3690875 and I think also P3412064 for this extra lenght shaft.
This is not the one with a bronze gear.

There is a longer shaft and there is a longest shaft. That system takes the longest. It takes a Milodon 21500. (It is 7" under the gear.)
 
So, I went to the Milodon site and the only kit that uses the plate is Dual Line Swivel PN#211160. At the bottom, they list 2 intermediate shafts steel/bronze so These should be longer appropriately.

Yes thank you. Looks this is the number to look for.
 
SSing,
I just went through this on a new pump!
I went from a Melling stock type replacement to a Milidon pump.
I purchased a Mopar Performance P3690876 and it was too long in my case.
This might be what your looking for?
It is 8.562" overall but more importantly it is 7" under the gear.
I have it listed for sale over in the performance parts for sale section.
In my investigation there are at least 3 different shaft length's in play out there.
It does have a bronze gear for roller cam engines.

Yes, thank you but I have to consider shipping and cost of a steel gear.
I see what I can find firest.
