I put AC vents in my painted 57 and used a 3 inch hole saw. Directions I've seen call for a 3 1/4. Do you have the templates for determining were to cut?
You do not need a long guide drill, once the hole saw starts cutting the drill is just hanging out behind the dash. There is nothing for it to guide at that point.
The sizes I refer to are for the original style vents.

No template...Thanks for the pic..any chance of a pic from driver's side?? I have kick panels w/ speakers & that caused the chezzee plastic duct (on driver's side) not to fit....what side of the emerency brake handle did you put the a/c duct... to the left seems tight...more room on right.Thanks:):)

Enlarge this until the hole measures correctly and it should work. If this doesn't work I have a full size paper copy I could mail, pm me if you want.

bob, are you trying to install some Vintage Air vents or stock reproduction vents? The stuff that Jim's showing you is for the repro's, which are bigger than you described.

You're probably on your own for templates and location with the smaller vents.

Are the vents made for a flat surface, or for a curved/angled surface? You'll need to "aim" your hole saw appropriately depending on that.
