You could just get aircraft bolts if you need replacements, I'm sure that's probably what comes stock one those anyway. Most everything on our racecars are aircraft grade, no grade 8 bullshit for anything worthwhile.. I can't remember the grade/series name of those, I'm getting rusty doing electronics instead of mechanical..
You should be able to get them much cheaper than through the manufacturer I would assume.
