Yes Joe, unfortunately a stock gas tank is pretty much vetoed, there just simply isn't room,on most A bodies, I've tried several designs to get it to fit, the strange thing is, and I have no explanation for, I have a 71 dart, and 71 duster, on the duster, there's almost 3 more inches between the tank and the pumpkin, than on my dart, so while it may squeeze into the duster, it won't on my dart, and I've checked to make sure axle locations are identical, so this was something new to me, and both have 8.75 rear ends, so if anyone knows why that is, I'd love to know! Anyway, as I go on designing, I may make a provision in the crossbar for exhaust, I think it's very feasible to do, unfortunately, with a suspension like this, they just didn't leave much room to work with.
