Early A door and ignition locks

Ignition lock cylinder is same for '60-'68. The '66-'72 trunk lock cylinder will fit and work in your '63. New door locks for the pre-'66 cars are difficult and costly. You can upgrade to the easy-and-cheap-to-buy '66-up locks without much difficulty; see thread here.

Thanks for the link, Dan, and I liked the mention of Greenlee chassis punches. They are awesome, but are becoming somewhat expensive these days. I first became aware of them when I was a kid, got my ham radio license, and wanted to build some radios that required punching round holes in a steel radio chassis. A Greeenlee punch can actually cut a perfect hole in a hardened steel bumper(!) (to mount a trailer electrical connector, for example), but it is important to grease the cutting edges of the punch up well before punching the hole. The grease makes the punch cut through the steel much easier.
