I need to replace the drink holders in my 1997 Sanger V210...it's the one with the carpeted step in the back that has two drink holders in each. All 4 of them are in some stage of brokenness and I want to replace them. It looks like the inside diameter is 2 3/4" and the depth is about the same. I've looked all over the web to no avail. Anybody know which current holder replaces that one? Thanks!
