Mike's right! The Classic Update Kit is the best kit for your application. It's compatible with Vintage Air, Covan Classic, Classic Instruments, Dakota Digital, etc.
It's a 21 circuit, 18 fuse, ATO style panel (bolt on type) that mounts in the exact place of your original.
Here's what it looks like if you wanted to take a peek at it:

It has complete color instructions and comes with headlight & dimmer switches, also. All GM color-coded.
Plus, you can bounce and tech questions off me right here on the board while your installing & I'll help you out.
Good luck with your project & have fun!
