Does anybody have any experience fitting these (newer) type of seat belts to replace the "floppy" versions that came fitted (in the US, at least) to the 1969 SL? It looks as if it would be pretty easy - and I do not care that it will not run through the chrome top piece - I care only that I can bolt the unit into place without any further modification to the car. The retractable reel version would be a definite improvement, and, since my belts are original, they are rather tattered and need to be replaced. One of the German suppliers whose e-mails I receive has them, and they look as if it would be an easy "plug and play" fit.
Anybody know anything about this?
Thanks.
