lowrider Posted October 23, 2006 Share Posted October 23, 2006 i hate to make a fool of my self,but i took the seat belts out to replace them with a 4 point harness. stupid me sat the seat belts to the side and lost all 4 bolts that connect them to the floor.i was wondering what size the bolts are that connect the seat belts to the floor.

2003z Posted October 23, 2006 Share Posted October 23, 2006 7/16" . I know it seems odd, but fed. regulations mandated that size bolt. Quote Link to comment Share on other sites More sharing options...
zcarnut Posted October 23, 2006 Share Posted October 23, 2006 2003z is correct. This was discussed on the Classsic Z Car Club Forum recently: The early Z car seat belt mounting bolts are SAE thread and not metric thread. This is due to the US DOT standards in effect at that time. Quoted from 571.209 Standard No. 209; Seat belt assemblies: ...Seat belt assemblies designed for installation in motor vehicles equipped with seat belt assembly anchorages that do not require anchorage nuts, plates, or washers, need not have such hardware, but shall have 7/16- 20 UNF-2A or 1/2-13UNC-2A attachment bolts.... You could either use the approved SAE bolt which has been already tested and certified by DOT or you could use your own bolts but you must summit your test data. Generally, it is cheaper and safer to do the former. Quote Link to comment Share on other sites More sharing options...
