20429339 is the GM part number for the hood release cable. You have to buy the ENTIRE cable. Handle not sold separately. PRICEY if you find a GM one. Lucky for you they have aftermarkets, if you don't mind one of those.
563762 is the GM part number for the emergency brake handle and cable. Again, the entire front section of cable with handle has to be purchased as one.
Gbody parts has a GM one for 70 bucks, but they also sell the repros. Nobody else does to my knowledge. NOTE: YOU MUST USE THE OLDSMOBILE PART FOR YOUR OLDS. Other G-bodies use different part numbers. Why? I don't know.
Here's a repro.
Reproduction Parking Brake Handle & Release Cable. Reproduction Parking Brake Release Assembly. Correct Pull Handle with the Words "BRAKE RELEASE" Outlined in White.

Headlamp switch is 1972717. MOST of the ones 86 and up had the "newer" design, with the light bulb with the light "rays" eminating from around the bulb. The 84-85 switches had the ovoid shaped headlamp with the light beam shooting out of one side. Those are very hard to find new. There's also a design for a short time that just says OFF instead of LIGHTS OFF. It was the same part number, but was intended for Ciera I believe. If you buy one strictly by part number, you don't know which you will get, but MOST LIKELY it will be the 86-88 version.

Here's an 86-up job. It works exactly the same, as all are the same part number, just the bulb icon looks different. Pretty cheap actually.

Pull the vent cover from around the switch. Then look on the far driver side to see if it still has the fiber optic lamp tube running to the side of the headlamp switch. There's a brass ferrule that attaches the tube to the headlamp switch that needs to come off. There's a couple of screws that need to come out and it should pull straight out. Don't get crazy and be careful with that fiber optic tube.
