Where can i find these parts??

[RapidRide2]

I am new to this board after just purchasing a 83' sierra. Does anyone know where i can get a excellent quality/or oem dash pad for this truck???? Are they hard to install??? How bout a new to excellent dash bezel (alum. finish) And i am also in need of a grille and new gmc letters for front&rear of truck. Has anyone ever repainted the grille and letters with good success???? Also since this truck is an 83' and has the "tacky" boss hog front bumper guards. Can these be removed and have carriage bolts installed???? I am also in need of factory wheel centercaps for the fact. gmc rallye wheel. Can any of this stuff be purchased from the dealer????
