UPDATE:

Received two new OEM hands from Taurus, one for an 85, one for an 83 (just in case the 85 part wouldn't fit an older 85).

Neither of them fit.

So, weld-job it is... Probably make some time on the day off Monday to get it built up how I need it.

I'm also kicking around with a machinist buddy of mine to see if we could CNC a new part, but it sure won't be as fast as a weld-job, but we may try it out anyway. He says it'll be the smallest part he's made so far, so it'll be fun to try out.
