I can not get my vendor spring spreader completely under the springs on both sides as my shackles are frozen. I've raised the frame so rear is off the ground and they stay in the same position. Jacked under diff and they stay the same position. Hammer a 2x4 under with a angle cut to wedge it in and it just conforms to a upward position towards spring. I have sprayed a whole can of "Deep Creep" and nothing...Oh, and long crowbar between shackle and axle. I have searched here a lot and have not seen a mention of shackles that have zero give. Even had a fellow model A'er tell me to just cut them off. I have new ones on order so I guess I'm going to break out the wheel....I have to get this spreader in so I can get the rear out as I'm prepping a new frame.
