Parts - Bodywork - Seatbelt anchor plates

The std. seatbelt anchor bolt is 7/16" UNF (20 TPI) The best way to effect a repair (see forum topic) is to use an anchor plate with pre-welded nut, but repair and reinforce if necessary, the whole supporting area before welding in the new plate. Weld plate from the back of panel of course, seat-belt bolt goes through panel, through anchor-plate and into anchor-nut.

3) Securon s/b anchor plates - Almost impossible to obtain at a sensible delivery charge, despite the fact that they list them.
