Remove front a-arms/spring tension when frame only??

[JamieGallien]

I just ordered my suspension parts to redo the whole front end, but I'm running into a problem with dis-assembly. I can't find spring compressors to fit/work and I'm afraid I can't use the floor jack method because I have the thing stripped down to frame only...there's just not enough weight to compress the spring and let the a-arm down safely. You guys got any ideas? Surely someone else got down to frame only and decided that was a good time to do the front end? Am I stuck waiting until the truck is reassembled to do this? Thanks for the input!
