Hi all. First post in a long long time here! Good to be back. My Mk1 has just been insured finally (I will update my build thread with pictures ) and I really want to fit my britax 3 point belts (before the weekend hopefully!!). The difficulty I have is that in my b pillar I have 2 chrome inserts punched through b pillar with the thread on the inside, but I am unsure of the thread diameter so I can get some bolts to fit correctly. I have searched around and think they should be 7/16 UNF and about 1.5 long but im not sure. http://www.minispares.com/product/Classic/GHF107.aspx

Also on the floor I have 2 holes where the U bolt would have been fitted to anchor the belt down by the sill, 22mm inbetween the legs with a thread length of 40mm, m8. I have found some but with something so safety critical I want to make sure I do it right. I would also use 3mm spreader plates underneath too. Are there any safety standards I should look for when buying bolts?

Lastly I need some door rubbers as I dont have any, any recommendation on what or what not to buy!

Thanks very much for your help as always its very much appreciated and any replies today would be great as I would like to order ASAP to get the bits before the weekend

Thanks Tristan

That arrangement with the U-Bolt is not at all what I have on my Mk1. (Your subject line says Mk2, your text above says Mk1). The Britax belts must use a very different anchor method than the Kangols in my car.

The U-bolt you linked to is stainless which I don't think is appropriate for a seat belt anchor. I am confident saying you would want a tough grade of regular steel, not stainless.

You are correct about the thread size but I cannot confirm the length of the bolt. I remember these as shoulder bolts, or large head bolts with a spacer tube on them. (See eBay item 141203046047). The intent is the triangular plate the belt attaches to should pivot. I have one such anchor point at the top of the B-Pillar and another one at the bottom, both threaded. I cannot remember the details of how the buckle end of the belt attaches to the tunnel but I know that its triangular anchor plate is also free to pivot. I know it uses a similar bolt but I cannot remember if it is a bolt with large washers against the tunnel or a weldnut in the tunnel.

I have no advice about the door seals except to expect to have to work a bit to get the doors to close properly again once you fit new seals.

Tris give me a call I have a box of seat belt bolts from later cars should have the horrid
belts from 9618 too for parts and a pack of samples for door rubbers from Phoenix Supplies

Thanks for the replies. dklawson thanks for pointing that out, thats a late night typo error! will try and change that.. Interesting they are nothing like your mountings. The B pillar has those threaded tubes (thanks for confirming size), by the sill there is just 2 8mm holes for the U bolt to fix through. For the tunnel mounting again there is 2 8mm holes where 2 bolts go through to a spreader plate on the outside.
I noticed those bolts on ebay you linked to and did ponder purchasing..

I will give you a call Ian..
