According to my parts book for the GMC the holding tanks are held in by 4
3/8-16X6" round head screws prior to 1975 and 4 3/8-16X7 1/2" round head
screws after 1975.They show the screws They go from the inside of the coach
through to the bottom. The front 2 go through the plywood floor only and
have 2 washers, and the rear 2 go through the plywood and a frame member
without a washer.
If you have an oak member someone must have modified your coach.
