If you're not experienced at spring removal or you don't have experienced help, you're going to need some quality tools to make sure you don't loose body parts.
I would definately get a good spring compressor rather than the method you outlined. I bought one from northern tools for about $30 that worked great on my '73.ok coil spring compression don't work well they do they just don't fit in there. I can use a floor jack ,ratchet strap and a person sitting on frame to get them in but the top of the spring isn't over in the dish spot it is actual across the shock opening
There's gotta be a easy trick to get the springs into the correct possession someone tell me what it is please
I have spring compressors tools I did see there is a internal compressor I mite order one of those if the hammer doesn't work
ya I had gotten the external compressors that didn't work was getting ready to order some internals but have them in place now, both front shocks and sway bar installed
