Crotch Strap too short

I received my harnesses from Hooker Harness and there is no way the crotch strap is long enough.  Scott told me they are the same for the RV-7, but actually the crotch strap is different.  He was very gracious and agreeing to fix it, I just have to guess at the correct measurement and send it back to him to fix.  From the center of the attachment buckle to the silver adjustable part with the red strap on it, it should be about 10″, not 5″.  That’s going UPS today.
