As this is my first post I'll introduce myself, I'm Rocko from Minneapolis and I bought my first T (26 or 27 roadster, 26 engine and 27 numbers stamped on the frame) 1 yr ago. It was a barn find that sat in a garage for 20+ years before I bought it. Although I'm 65 and have put together many rods, it has been a real learning experience and this site has been a wealth of information. Luckily, almost everything on my car was there except for the gas tank straps. I could make my own but I thought I would first see if anyone makes these or has an old set I could buy to save me the trouble.
I have a set, call or email me; firstname.lastname@example.org 320-293-1953
contact Mike Peterson, the gunman63 he can surely help you.
I haven't had a '26-7 for years, but as I recall there are rubber cushions placed between the gas tank and the straps.
There are rubber cushions that rivet to the straps, There are also two anti squeak pads that rivet to the firewall on 26 models (early?) you will have rivet holes for them in the firewall if your car used them. or there was a cardboard anti squeak pad that fits between the tank and firewall (late 26 and 27 ??) Im not exactly sure of the changeover time and Im not at the shop where the books are. Langs and the other vendors sell the pads or cardboard liner.
In addition to the rubber pieces on the straps, there also is webbing on the upper part of the cowl and where the tank makes contact and the firewall. The vendors sell these with an adhesive backing since it is difficult to get rivets in the top pieces.
