Sorry to take a bit to get back to your thread KWIG61. I did some more research earlier based on your plate info, but then it was dinner time so just now getting back to it.
Here's what I gathered so far from the data on your Protect-O-Plate:
VIN = C1545S227527 - decodes as:
C = 2 Wheel Drive
15 = C10 Long Bed
4 = Pickup
5 = 1965 model year
S = St. Louis Assembly Plant
227527 = Sequential Serial Number
Paint Code = 555 - Two tone paint with primary color "Fawn" and secondary color "Off-White"
Engine = F0802WE - F = Flint Plant 0802 = 8 February build date WE = regular production 283 V8 175hp 2G carb with Powerglide Transmission
Rear Axle = HE0708W = HE = 3.73 ratio 0708 = 7 August build date W = Warren, MI Plant
Transmission = C0805 - C = Cleveland Plant Powerglide for 250" L-6 or 283" V-8 0805 = 8 May build date.
Below are some screenshots of the resources I pulled this info from, except the VIN decoding which came from
this LMC resource PDF, which also includes the basic engine two letter identifier.
I think this pretty much covers your info.
