Most of the bolts are accessible except for 2 on the top part of the pedal box. Well, if you have cracks that you want to fix on your dash then you might as well do it all at once cause you have to pull the dash to do that. Make sure you get the pedal box for a 240z and not a 260z/280z, the bolt pattern/booster is different. I know cause I bought a 240z box and just found out the hard way that it does not fit, but I think I'll be able to transfer the pedals to the auto pedal box.
