I am in the process of re-doing the entire inside cabin cousions and making the three that go over the toilet and span the walk way down below. I have bought all the fabric 11.5 yrds, I hope that enought. Some new foam for the new cousions and monel staples, t-nuts to replace the rusted ones that GW installed on the marine grade plywood. Don't know why it was not SS? New 2 in. webbing for the top bunk, new thread. Need to purchase 4' x 8' marine grade plywood for the two new cousions. I recieved some emails and pictures and measurements from a guy that has a 2000 Gulfstream. I hope they are the same size, if not has any one performed this same build or can get me detailed size and mesurments? Thanks, Joe W
