As some of you know I am currently restoring a station wagon rear body to drop onto my hardtop before then restoring the station wagon at a later date LINK.
I am beginning to look at the seatbelt mounting. I have all of the brackets now, and have front belts, I am hoping to find some rears at malvern tomorrow, if not I will buy some new ones. I have some of the bolt from dismantling the old body but some of them are either very rusted or were missing as it only came with a single static belt in the rear. Looking at my parts manual the fitting kit for seatbelts is STC1180 however this kit does not look to be the same as the spacers I already have. Below is a pic from google for the kit STC1180. However I the spacers removed when disassembling the rear body were stepped spacer pictured second (generic non land rover). The belt buckle sits on the spacer step allowing it to still rotate. Can anyone confirm, is that what the shoulder on the bolts do, allowing for the same thing but with a special bolt rather than a normal bolt?

Ive had some tube things (which are probably the spacers in your photo) knocking about here for ages, wondering what they were (they're part of my 110 300tdi station wagon, but I couldn't work out what)

They must be somthing to do with the c post high level mount, as the lower belts are still in place on mine.

Possibly somthing so as the trim doesn't crush when you do up the belt mounts?
