It was in the neighbourhood and almost a giveaway because it didn't seem to work properly. At home I cleaned it and oiled all the bits that were indicated by a red dot. I found out the bottom part was overoiled and the head was cork dry. Apparently these people didn't know you have to pull the cover off to get to all points. Once everything worked I was stunned by its power, punching easily through multi layers of vinyl and even carpet (did some edging).
So I just had to try it on the biggest challenge, a new racing harness. I have a red Sabelt harness, but obviously a blue car needs a blue harness. I found the correct webbing in Germany, slightly thinner but still 15500N breaking force and ofcourse Polyester. I calculated total failure would be around 100g, safe enough considering 1 second over 40g is deadly in a crash.
After a few test pieces I measured up the old harness and cut it to bits:

Then stitch the whole thing together and without too much hassle I have a new racing harness tailored to the car:


(standard harnesses will never fit properly, my old Sabelt harness was shortened and still it had too much slack when fully tightened).
Anyway if you are going to do your own interior take a look at these old grey Pfaffs. Mine is 50 years old and it is like new. No modern machine can beat it unless you want to spend hundreds of pounds. I paid 30 euros for it (but now everything is working again it's worth about 200 euro).
