If you feel it's safe, then run it.... I don't like a spring anywhere other then on top of the axle where it is intended to be. Yeah, I know, everybody runs them in front or behind the axle without problems. But from a design standpoint, the spring located anywhere other then on top of the axle is putting extra stress on the component it's bolted to. The leverage point for the spring mount behind the axle is at the attach point of the spring eye to the axle, not the correct place. When the suspension moves up and down this also places an undue outwards force on this same attach point. The movement, though minimal, does put stress on the attach point and the attaching hardware and IMO is an unnecessary stress. Probably not a big concern with most, but it is with me...

Just because everybody does it doesn't make it right. The spring is designed to pivot at the centerline of the axle for a reason, to prevent undue stress on the other components..... BTW, proper welds would also require heat treating. More to a strong and safe weld then it's looks. You'll be welding different materials, a cast or forged axle housing to plate steel..... There is a correct procedure to heat treat this weldment to ensure maximun strength....

Hey, it's your car, do it however you want. I'm just expressing an opinion, not saying that you are wrong, or looking to start another argument. Not my car and chances are my butt will never be in either seat.....
