'Tramp,
Are you talking about just bolting the springs to the axles without welding the spring perches to the axles? If that is what you mean, I think that if you are doing it just so the car is mobile so you can move it around, that shoud be fine. The worst thing that could happen is that the axle tube rotates with respect to the spring, but if nothing else is hooked up (e.g. brake lines) it won't hurt anything if it moves. L8r
