RCU Forums - Excelleron 90 problem

I have an Excelleron 90 that has an odd problem. The upper elevator pull-pull cable exits are at different heights. The left side is at 4 5/8" up from the bottom of the fuse as per the manual and the right side is at 3 3/4" from the bottom of the fuse. At 3 3/4", the pull-pull cable would rub against the top of the stab. I have emailed Hobby People but haven't got any response from them. Has anyone else had this problem? It looks like I'll have to open up the side to fix the problem and was wondering if anyone else had to do this and could give me some advice.

Thanks!
