For the wagon pinks in the front I used one compressor covering two coils and the other compressor on the other side covering three coils. The line that connected the two compressors was either perpindicular or parallel to the strut ear (can't remember). The main PITA for me was to get the spring uncompressed and have everything keep alignment (rubber isolators seated properly and the 3 tophat holes facing in the correct direction). If you don't have anything to hold the strut and are only using hand tools you kind of have to be a brazilian jujitsu master to simultaneously hold the strut assembly and wrench the compressors (at least for the cheapey Harbor Freight compressors I was using).
Try using a hose clamp or two around the mousepad and grabbing the tails of the hoseclamp with the vice grips. It always made me nervous vice gripping the shaft.
