I know this has been covered a number of times before but does the 5/16 UNF nut have to be welded to the chassis even if it can be accessed? Plus is there a problem putting the nut inside rather that out. I am struggling for clearance to the fuel lines if I stick the nut the tunnel side?

So is a nyloc nut not welded to the chassis
fitted on the inside o.k.?

I must get me an SVA manual trouble is I don't thinnk I'll have the time to work out what it means!

I dont think 5/16 bolts are the right size try 7/16 or 11mm i think

yeah sorry my mistake they are 7/16....question still stands though.....

If the Velocity is the same as the Luego Locost it has small triangular fillets welded to the chassis at the seat belt mounting points. What I did with mine was to make some plates 3mm thick that fitted in the tunnel and drilled a 7/16" clearance hole through the fillets and the plate , then welded nuts to the plates. Made them easier to fit than nylocks

I can get to the plates no problem but just wanted to make it easy...If nylocs are o.k. then I would prefer to go this way!

Thanks

If the nut is not captive then i think you have to be able to access both the nut and the bolt-head from the driver's seat
