Prine: i sure could use some of that energy you have over here at my shop. Man. You're a ball of fire. What do you do in your spare time?
On the gas cap...the first pics i couldn't see very well but now that you showed it up close there is no doubt whatsoever. It is definatly a cap off of a 37 Henweigh. Confirmed that for ya.
