I am looking to fit 4 point harnesses to my classic.

The eye bolts in the front seats are already there thanks to a previous owner.

Can anybody tell me the exact size of eye bolt I need to get to go in the back in between the join of the rear seat??

 

7/16ths with a fine pitch thread (1.25mm)

 

Thanks for that JonMc. Best place to get a couple?

 

Demon Tweeks, Rallynuts, EARS, Merlin Motorsport or ebay, to name a few. Plenty on ebay for pennies

Is there any length better suited or doesn't it matter?

 

Not really sure, you'c have to look at the thread length in the car and make sure that the bolt goes through it all. Also worth checking behind for clearance, and if you go longer then it's no problem. I've used a harness bar so mine are mounted differently

 

Thanks.

Thought I read somewhere that the extra long bolts get a bit close to the fuel tank. Will find out the length of the original bolts and get the same.
