It’s out of a manual bw1354. The rest of the case is a bw1354 electric shift . Yes, I’m learning how how of steel it is lolwhat year?
that looks like a roll/tension pin. they are a very hard material so good luck drilling it.
try carbide tooling.
does that hole have rear access?
if drilling it would be best to mount it in a mill for precise work.
