CAUTION! I DO NOT sell these on eBay. There's a scalper on there who claims to be me and they're selling my model in breach of the non-profit licensing terms. They're also using my description and photo. The quality of their print is crap and it doesn't work. Report any eBay listings and just download the model free for yourself. https://www.ebay.com/itm/256825606319

Hey.

This is another functional-fix that I did for a personal project but it might be helpful to those of you with BMW's of the same era.

The problem is that the plastic slider bushing thing on the rear window regulators gives way and splits in two. You'll often find the remnants of it in the bottom of the door. This causes the glass to move sidewards when moving up/down and can damage the rubbers by causing them to fold inwards.

The part isn't available as a replacement piece as it is riveted to the regulator so I designed this part in such a way that it can be installed without removing the rivet. It simply replaces the original 1-piece item with a new 2-piece part.

Installation is pretty straightforward and it should hold position by friction alone, although I opted to stick a rubber o-ring on the neck of the new piece and this helps to keep both pieces tightly held together. You could also use a small drop of glue if you are worried about it coming loose at some point in the future.

Anyway, I realise this is pretty niche but someone might find it helpful. :)
