I found this on the Billingsley Racing website. That may be a great answer to a common problem of where to mount your anti-sub belt (if it will clear the seat, I've not looked at the mounting location recently). It appears to mount to the front seat mounting bolts (I've E-mailed Amber Billingsley for more info about it). I'll post more as I get the info.
