shoulder seat belts on a 70?

[travisfraughton]

I'm looking to put in some shoulder belts to replace the stock lap belts. I am wondering if it's as simple as just popping out the little cap and bolting it in.

Also, I see that Yearone has a universal 3 point non retractable belt that actually comes in orange (great to match my truck) and also that yearone also sells a pair of seat belt retractors for about $45.

Can you combine the non-retractable belts with a retractor to make them retractable belts?

If not I doubt I will order from yearone, as classic parts has a retractable set-up for around $90.00. I can't seem to find if they sell em in pairs or singles though.

Has anyone ordered from classic parts before? if so what was your experience.?

Thanks for any help.
