Audio Systems: New Deck/ Old Car, nibbler, ranchero

Question
Hi, i have an old '66 ranchero and i was wondering what is the best way to put a new deck into a car that had the old two pin knobs. I dont mind cutting into the car, is there a kit that works best for this?

thank you

Answer
If it's a metal dash, a power nibbler works great (try Makita for that) if it's plastic you can use a small hand saw. It's more art than science, have some trim rings to use with the install sleeve (can) in case your finished edge looks a little "rough"
