[more ambition than brains]

Most tool truck sales people,( snap on, mac, and matco) should have a spring compressor tool on the truck. It is made up of two stamped steel channels with notches at one end, center has small collar style bolt. open tool to width of spring when hinge open, slip deeply into into outer spring coil ends, tighten center compression bolt. Spring gets small enough to easily, & safely remove. Works on or off car. Not expensive, mine is 15 years old. Works on almost any door hinge spring. Really handy to have in your tool box.
