I was washing my 1996 coach and broke off the nipple that the windshield wiper hose connects to on the front of the coach.   I have the dual arm wiper and I would like to know how I can get behind the fiberglass front to put in a new nob and hook up the hose?  Can I pull out the wiper assemble by removing the bolt and then prying it away from the fiberglass front?  It looks like it is sealed with putty, so not sure I want to pull it out if there is a different way. Any advice?

Thanks,
Jerry
