Going to get after this 57 D100 short narrow box again. It's on a 79 frame now but it just doesn't look right. So I picked up a 94 Dakota and I'm going to start over. The 94 has a 318 magnum automatic and is fairly low mileage so I think it will be a good starting point. Hopefully the air conditioning, cruise and other goodies will make the trip. Anybody know off hand if the Dakota gas tank will work when I take about a foot out of the length of the frame?
