Hey guys,

I have a 1965 GMC K1000 4x4 with the 305E V6, and a 4spd manual transmission. The starter was shot so I replaced it (with a new WAI 4038N). The new starter makes a "clunk" when trying to start maybe 1 out of 4 times (not consistent). The other 3 times it starts just fine. In troubleshooting so far, I've done the following:
- bench-tested the starter (fires 10/10 times no issues)
- tested continuity for all the wires from the ignition switch to the starter (all good)
- replaced the starter switch with a new one
- sanded the blade connections on the female side (plastic block) where the starter switch plugs in to the wiring harness

Any ideas? When it makes the "clunk", it sounds like the bendex is hitting something and not extending all the way to engage the flywheel. Does it maybe need shims? There weren't any on the old starter.

Thanks in advance!
