Wanted to use the Federal Interceptor Siren from the Cadillac in the Pontiac. Cleaned up and sandblasted the center console, added a water temp gauge, power outlet, modern fuse block on the inside, and an audio plug to the radio input for parade music. Color matched the siren case to Valspar Spray Paint from Lowes. Had a couple bad capacitors that took out the PA and Radio side, but I was able to repair that in my shop for $1.00 in parts.
