I was tightening the bolt that attaches the ground wire between the chassis and the engine mount on the passenger side and the entire boss for the connection broke right off the mount! (this is the bracket for the hydraulic engine mount)

The mount looks to be in good shape outside of that.

Should i drill and tap into the mount, or is there a better place for a new connection? The wire looks pretty short to go anywhere else obvious... I could extend it with another piece of what looks to be 6 awg?

There isn't enough of the old boss to drill and tap into that.

 

If anyone else does this..

there's a large bolt holding a metal clip that holds some cabling that is just down and behind the vapor recovery module on the passenger side of the engine.

looks like a pretty decent ground point. VERY hard to get to. Needed to use my crows-foot and ratchet as kind of an offset wrench.

I don't know why such a large bolt was used just for a conduit carrier bracket...
