I'm assuming they cannot be repaired.
Salvage won't sell them separately from a hatch.
Does anyone have any suggestions for where to get these?

 

Fcpeuro.com or ipdusa.com

or ebay

 

used ones likely would be half worn anyways. get new, they last 5-10 years before they start to sag.

on my 740 wagon, I just replaced the guide pieces on the side that the door slots into, now it closes much better, without slamming, and doesn't squeak/rattle any either.


(the black thing next to the light... this pic is 'before' the replacement).
