Hi all - I've used the "norprene tygon tubing" hack to fix my tu-58 drives but now I'm faced with an Archive Viper 1/4" drive with a *seriously* gooey rubber roller... Has anyone gone the route of ordering a replacement part? Or shoud I just try a smaller diameter piece of tygon tubing? :-) I think I'd like a 'real' part if those can be had. Advice? -brad
