It's time to replace the bellows on my 2002 Glastron 5.0GL / SX drive. Loaned my SELOC book to a friend and haven't seen either in a while. Haven't seen much Volvo stuff on-line like Merc has. I can remove the drive with no problem and have pretty good access to the clamp that holds the boot to the transom end but what holds it in place on the back end closest to the outdrive? Thanx in advance..
