I've finally gotten around to making progress on dropping the Legacy 2.2 into my Brighton but I've hit a snag. At some point the bolts for my pressure plate grew legs and eloped. I've searched the usual part supplying suspects but have been unable to locate any O.E. replacements.
Have any of you ever slapped in some hardware store grade 9 or better bolts of the proper diameter, length and pitch in place of the stock pressure plate bolts?

The diameter, length and pitch is easy to find. The hard part to find is the shallow head. Either a Soob dealer or junkyard are your best bet. FYI, The bolts for a MT are slightly longer than the bolts for an AT.
I found some bolts of the proper dimensions and 10.9 grade but when the stock bolts left they took the throwout bearing retainer clip/spring with them.

I was in the same boat (different application) with needing bolts for both a flywheel and pressure plate and having a difficult time finding them. Fastenal, Grainger, McMaster Carr all have just about any size, pitch, grade and head style. However, with the amount of bolts of unknown origin, steel specifications and quality out there it is too big a risk in my opinion. The very last thing you want at high RPM's is a flywheel or clutch failure due to fastening hardware. If you know the sizes (diameter & pitch_lenght and head style you can probably match something up with ARP (http://www.arp-bolts.com) Bolts. You will probably pay a bit more but the peace of mind is worth it. I would not use bolts from a scrap yard that may have been over torqued. I had a high RPM clutch failure one time and was very lucky I escaped injury.
+50 for the ARP bolts in this application.
Having a pressure plate let go at speed can be like the blade coming off a running radial arm saw. It may not hit you, or it could be really nasty.
pirate is correct: don't scrimp in this area.
Don't know where you are, but, try Chesapeake Fasteners, they sold every type and size of bolts known to man, it seemed.
I have read one can get too high a grade bolt, for, yes they are "stronger", but more brittle and not as ductile as a lower grade bolt, and I think the correct ductility would be wanted in a clutch/flywheel application
