Seatbelts?

[Oregoon]

Hello, all!

My '74 GMC Standard Cab is my daily driver, and it features lap-belts.

While I dig the clean look of an uncluttered cab, I like being alive and feel that some shoulder belts would be in my best interest.

From what I can see, it looks like a case of finding the appropriate color (in my case, Golden Brown/Saddle) from a donor truck, and bolting them in.

Am I correct, or is there something I need to know? Are shoulder-belts the same in all years of squares? Any other years/models that will work?

Thanks in advance.
