I have a 928 1981 4.7 s2 , I have replaced the front seats with black leather and wanted to match up the rear seats , I found some on ebay and purchased them but I did not realize that the fittings are different where they go into the centre tunnel area . my old ones have just a bar that goes into a hole and the newer ones have a large angled bracket . Does this mean that I have to get a different tunnel cover or indeed change over the leather covers with the old rear seat backs , which do look a bit different in thickness .If I find a new tunnel cover will this solve the issue . many thanks Trevor in the UK.
