fwiw, I put klippan k7178 & K7179 in the front of my mk1 capri in 2007 when it was going to be a road car.
I also put 2 x K2257 lap sash belts in the back
They all came out last year when the harness went in for the track.
They are all in the shed almost brand new if your interested, or anyone else for that matter.
i only used the car a max of 1/2 a dozen times a year so the front ones got used maybe 25 times..
