Removing 1955,1956,1957 Chevy hood hinge springs, hood spring, spring

Replacing old Hood hinge springs on Chevy. We lower the hood and far as possible then stick as many screw drivers in the gaps as possible. Causing it to expand when spring compress. To pull out of hinge. Can possibly try this on other cars like Ford Merc Pontiac Cadillac belair,210, Hardtop others too. Good luck.
