I have recently discovered that my 2004 FG649 is missing what the shop guide calls "helper spring stoppers" (part #22 in the diagram below). I found what looks like the right part on eBay:
Unfortunately, the ad only lists a few FE models, and the seller doesn't seem to know much else about them. The part number is MB104718 -- does anyone know if this is likely to work on an '04 FG? Or maybe there's a non-OEM substitute out there that will do the job just fine?
