If you don't like the looks of the bolt ends and nuts use 'T-nuts" on the outside of the firewall. You can find them at most building centers with a good fastener section.

For comfort yes ditch the pedal and go with a round one.The gas pedal will be over the tunnel how far?depends if either of you drive righty,lefty.right gas left brake.I'm trying to concoct a pad for my foot to rest on still working on it.When you figger it out post some pics.I thought about those, do they make different grades? Like grade 5 or 8?
Yeah the gas pedal will be interesting to fit, I am pretty sure it will be sitting over the tunnel, or at least close to the edge.
I may change out that brake pedal for a smaller one, its a bolt on pedal so I can swap it out.
Opps sorry i thought you were talking about your Right foot on the trans hump.I just put my left foot on the floor as far as it will go the right foot is a pain cause you have to balance your foot half way up the hump.I have been using 'T nuts" for a long time and have yet to have a failure. I have even used them as nut plates for things like tail light mount thread inserts in frame rails.
Another idea for a foot reat for your left peg is to make up acopy of your brake pedal, weld it to a plate and bolt it to the floor. It looks like a clutch set up then.

Jim i messed up when i put my pedal in i put it to far over the hump and now i pay the price i have to kind of ballance my foot.Rick, if you notice in my pictures, my right foot is in the "normal" position with my heel resting on the floor. This makes for a very comfortable driving position just like in your every day driver. Ergonomics is very important in any of my builds.
