Just a head up on the 4pt harness you want to install. The proper way to do it is to use a roll-bar (Autopower) so the angle of the belt is at the right degree. For some reason, a lot of people mounted the belts to the floor pan which would result in a broken back if there was ever an impact. That being said, I wouldn't recommend a roll-bar on a daily/street car if you like your head being round.
Also, good luck with your project! Reminds me when I started mine 16 years ago.
