Pull the headlights, goto GM and ofer the 30 dollar blinking housings, then goto Advance or autozone with your old bulb socket and get 2 new ones. Splice the bulb sockets into the wiring, replace the bulb socket. Quit being a cheap ass and fix shit the right way, no wonder you have a 6 cyl, god didnt want you to punish an 8 cyl...
