This should probably be in the "Interiors" forum, but not much activity there lately. Anyways, do any of you have a few words of wisdom for mounting lap belts?

Judging by the large washers they give you with the kit, it looks like you're supposed to bolt the ends directly to the cab floor. That shouldn't be a problem, but my concern is the actual location where they will be bolted. I'm afraid that if I don't get it right, there'll be too much extra belt length on the buckle side.

Any help or rough measurements would be appreciated.
