Seat Belt Cert Questions

I bought one set of latch type belts. Two days at the track and those were gone.

I bought the cam lock stuff and sent them in to recert. No way was I screwing with latch belts like that.
I have a set of Crow belts, both sides, that are camlock. I will probably send them in to be recerted, if it's less than $100. Unfortunately, Crow used to be local, but they moved. Now I have to ship them
(Might send in passenger set too, then use it as driver side in my other car.)
