I just got through putting a tank where the spare used to go. It's a 19 gallon blazer tank sold for the 67-72 conversion. It's metal and came with the straps, tank, and sending unit for $250. Pretty cool. I mounted the fuel filler neck under the driver's side rear fender, just behind the tire. The neck coming off the tank was an odd size, but I found something that would work. I wrecked my '88 Honda Civic HB, so I pulled the entire fuel filler neck and cap, and it was the right size. Pretty cool stuff. Email me if you want pics. John. [email protected]
