Hi. Pops. What color is your truck.

Re: arm rest installation
 

White. Gold/beige inside with white door panels.

The arm rest in my truck, a 66 custom was not red or black, it was the gold/fawn color. ClassicParts.com has the arm rests, but like you said only in black, I think (Product #19-641). They also have the cage nuts ( Product #19-691). The arm rest is $17.95 and the nuts are $.75 . Good luck.

The gold or fawn armrests are out there. 67-68 trucks use them also. A couple of months ago I gave a pair to a friend for his 67. The green and red ones turn up also. Barry

I found a template image via Ray's chevy restoration site:
rmcavoy.freeshell.org/arm_rests.html
I believe this template is for a chevy truck. Would GMC be identical? sure would make life a little easier. i would still use two methods before drilling, but it would give some assurance in the process.
Other images give me the impression that the armrest screws meet the caged nuts at an angle. This could be a BIG deal;making a template very important. Also using the bolt and paint method. Yes or no?
