Sub-frame connector install ~missing bolt or not?

I just received a set of BMR tubular sub-frame connectors from Thunder Racing and was reading through the install directions (see here: http://www.bmrfabrication.com/instructions/sfc001.htm )

It says "Using the provided hardware, slide bolts through subframe connector, subframe, and control arm and install nut finger tight.

I did not receive any hardware. Do I need a longer bolt to do this install and anybody what size? Thank you

From the photos you linked, appears they reused some rusty old bolts.

BMR should have sent the correct length bolts with the sub frame connectors.....mine came with a pair/

thanks guys.
