2008 35 fountain lighting Cabin Door Problem
 

Cabin door roller on the bottom slider is busted cannot get one from fountain, they suggest I replace both rails and purchase a new kit. They mismatched the door to a different rail kit that the door manufacturer does not supply!!!Would not be a problem but they told me it is a very tough job not fun. Just trying to replace lower roller does anyone have any ideas on who may be able to fix something like this? or where I may obtain a part I have tried everywhere I must be missing something it should not be this difficult!
