Hi folks, I took out the rear 'dicky' seats and their mounts, and slid in my false floor and even manged to get some holes lined up pretty well. The four existing Nissan bolts are too short to go through the thickness of my false floor but I'm keen to secure it down. I took one to a bolt place and the guy confidently said "Oh yeah mate that's a _______________" - I have forgotten what he said of course but he sold me the four I needed that were a bit longer.

They don't fit - the thread is off.

Can anybody tell me what I need to know to find/order/ask for the right thread?

2003, GU wagon.

Thank you, Peter
