Hi guys i came across these on ebay
http://www.ebay.com.au/itm/NEW-SEAT-BELT-RETAINING-PLATES-BOLTS-FX-FJ-FE-FC-FB-EK-EJ-EH-HD-HR-HK-HOLDEN-/170701894456?pt=AU_Car_Parts_Accessories&hash=item27bea03338i'm sure that all sharp edges have to be rounded off to stop pulling through the floor on impact
and i was in conversation with a guy who installs seat belts and baby seats as his trade an sells similar brackets for approx. $3.00
if you read through seat belt threads on here you will find ( and confirmed by the above installer ) that the area circumference of the plate has to equal 3" square
correct me if im wrong, as i dont want to post things that aren't right... but this is the information i've gathered
hopefully this might help some out there who are in the same position
rusty I'm keen to know the measurements and thickness of the bottom pillar bracket.... that really looks the part
thankx guys
