1967 c10/c20 Restoration Value -which way to go

[95gATL]

Hi folks....
I have a '67 c20 small window fleetside truck that I am in the process of restoring. I've decided I have WAY too many vehicles and one must go and this one is it. Here are details on the truck:

67 small window long bed fleetside.
ZERO rust under the truck.
SOLID floors, never been repaired and zero rust.
Under the battery tray is only rust in engine compartment
Couple of small bubble rust in both door area that are being cut out and repaired.
Very straight truck

Matching # 327 v8
4 speed floor manual (matching with what came w/truck).
Power steering. No A/C, no power brakes.
Engine was rebuilt .30 over and brand new clutch.
147,000 miles on the truck. Drives well.

I'm having the interior redone to factory original (IE: seat cover, black dash pad, and black floor mat).

So my biggest question would be about the paint. It was originally a BLUE AQUA color. It is painted a SILVER color now which is faded and needs to be painted.

What is going to get me the highest price when I sell it....? Change back to the factory BLUE AQUA...??? Or keep the silver color and respray??? OR another color???

I can look at NADA value all day long but really don't think a truck like this will be worth 20k-30k...? Maybe i'm wrong.

Constructive and positive comments are appreciated......
Thanks.
