Not a Mopar but I have a question.

Ok, don't shoot me but I need some help. I work on most any old classic car. Right now I have a beautiful 57 Bel Air in my shop that I'm working on for a good friend of mine. The original hood is heavy and the old hood springs just can't do the job any more. I bought a new set and wanted to ask. Any body know an easy way to replace the old ones?
