Hello all,

I'm looking for a domestic source of top-quality engine bolts to mount up a 3W75 to a half inch thick firewall in a warbird. I'm queasy about the usual stuff of doubtful quality and origin (think East) you usually see in the typical hardware store. That stuff is ok for a deck in the yard, but not my application. Any suggestions as to a source? And, does anyone out there have any experience with safety wiring bolts like on full-scalers?

Thanks in advance,

Phil
