I live in North county of San Diego and own a 1925 Buick Standard. I'm looking for a referral for a machinist (old fashion kind with a lathe) to modify a hub puller I have from its current 2 5/8" threaded to 2 3/4" threaded needed to pull the hubs on the rear of the '25 Buick. Everyone I used to use has closed, retired or only do CNC production now. Thank you for any assistance.
