There is not enough room between the drum and wheel opening lip to mount my rear wheels. I must be doing something wrong. Rear of the car is sitting on stands which are sitting under the frame, not the axle. Tires are 225/75-15. Is jacking up one side at a time the solution? Is the fact the my car has police rear spring part of the problem? Stiffer springs aren't allowing the axle to drop far enough? I could put a bottle jack between the frame and axle to force the axle down further. But I know it shouldn't be necessary to do this. It shouldn't be this difficult to mount rear wheels on a 73 Fury. Thanks for any help.
