[Closed] Marin Mount Vision 2007 Upper Shock Mount

Noticed a small amount of play in the upper shock mount on my Marin. Having owned this one and also the previous incarnation of the Marin I have only encountered wear on the lower mount - not the upper. I have done a few tinternet searches and found loads of sites advertising the lowers but nothing specific for the uppers. I'm sure if I speak to BETD,MOJO and Tim Flooks they will be able to sort a replacement out for me but I was wondering if any of you guys had needed to replace the upper bushing, and also where did you buy it from.
