I have a brand new 68-0050 A65 oil pump worm. What is the difference between this and 67-0642 which is the same for the A7SS/A10?
Is it length? If the 68-0050 is longer, could I not have it skimmed to length?
If so, what is the correct length of 67-0642? 68-0050 is 21.75mm
The threads seem 20 TPI in both cases.
Urgent assistance needed as my rebuild has come to a dead stop, and I have a show deadline. Thanks
