New seat belt webbing and bolts?

Has anyone replaced their seat bets (new webbing) and anchor bolts? I am cleaning up the frames and would like to install new belts when putting everything back together. (I am also hoping to install lithium batteries :)…)

I worked with seat belt planet on new belts. He has replacements for Gems. Great company to deal with.
