Changing Seat Belts

[the_gambler]

Hi, I have a standard seat belt fitted to my hood, and wish to upgrade it to full harness. At present I have 2 floor mountings, and the third is on the cross member of the roll bar directly behind the seat at head level. I don't want to drill another 2 holes per seat in this bar, so I am looking for a full harness with 3 point fixing. The problem is all the 3 point harnesses I find have a long strap at the top, which look as if at their very shortest adjustment would still be too long. Can I use a 4 point harness but have the top 2 fixings on the one bolt? Or does anyone know a supplier of a three point harness with no elongated top/back fixing? Thanks for any help that might come.

A few do come with short top straps, Sabelt do, tho some one will put me right dont it have to 4 point mountings

Demon Tweaks. Rally Design, have a look at there catalogues loads of short 3 point fixings.

I've fitted both 3-point and 4-point harnesses to my S7 which does have rear mounting on the roll bar. the harnesses do shorten down quite considerably. The attached pic is not the best but does show the general idea.

Hi Colin

 

I have 4 point harnesses on my 2b with both shoulder straps onto the single welded tube behind the seat.

 

Passed SVA with this set up.

 

Most early 2b's have only two welded tubes.

 

About 2003/4 tricky started to fit four tubes, two for each seat.

Sorry - I should have said that the 4-point harness on one mounting point satisfied the SVA man. He did want to see a long enough bolt that it filled most of the threaded tube.
