I thought these days were gone? But, in measuring the centerline of the armature to machined mounting surface of a rebuilt starter with a dial caliper, it looks like I will need a .080" shim when installing this.. Wondering what others have found.. Mike

Never had an issue, but then again, if it'* not an AC Delco starter, you may find issues. Every manual under the sun says no shims are required.

yeah, can't find a manual with shimming mentioned, therefore, can't find a clearance spec with the pinion engaged either, but I still have the old starter, I will light up the solenoid, hold it there and measure the gear teeth clearances, and go from there. Overall a pretty good rebuilt starter, I took it apart, it has needle bearings instead of bronze bushings, armature and stator windings look brand new, also looks like a fresh mill-cut has been taken off the mounting surface, which would explain the need for a shim. Other option is using the nose piece off the original starter, just swap out all the inside goodies, nothing is wrong with the original nose piece. By the time I priced out a new solenoid, bearings, drive, brushes, it was much cheaper to get the top-priced rebuild, which came with a warrantee.. they even let me pull it apart before I bought it to see if it has needle bearings instead for bushings..
