Bolt size for strut tower brace install
How long of bolts should I use to install my Jamex STB? They appear to be 5/16" or 3/8" width holes (haven't measured yet), but what length should I use in order to clear everything?

The bolts that attach my Hotchkiss STB bracket to the strut towers are 5/16" by 1" long. The guage thickness of my bracket is about 4mm.

Cool thanks a lot, that's what I'll be buying tomorrow 
Probably a good idea to use washers on the underside of the strut tower right?

Yeah, use a washer on both sides, bolt head and nut.
A Hotchkiss uses a wide fender washer on top and a very small diameter (in comparison with the bolt head diameter) zinc-plated washer on the underside. It's not an USS or SAE washer so I guess it's a AN or something.
