Thanks Don and Bob...I figured I would just get the biggest one I could fit and I think that would be 17" long. Bob - I think the next car will be a little bit lower budget and I have the perfect canteen just like that one in the picture that I can use Does the 'next car' always start when you're looking at the leftover parts and think what kind of car they could build? I have a '35 front end, 283 w/ 3 duces and corvette valve covers, a 55ish chevy 10 bolt, and a cool 60's jag seat. I think it all would make a great A roadster or 5 window.
