'72 C-10, 402, is there a way to tell....

[Peepaw]

..what day my truck was made? I have got a manufactures date of 5/72, but was curious if there was a way to tell what day it was actually made on? I wasn't sure if Chevy's records got THAT specific, to be able to tell the exact day a truck was assembled, but figured you guys would know one way or the other.

The truck in question is:
1972 Chevy C-10 Manufactured 5/72 GVWR 5400
VIN CCE142A166054
W/Base 127
Model CE10934
C60 4 season air condition
J70 Hydro Brake Booster
M49 Turbo Hydra Matic
U37 Cigarette Lighter
525 Light Yellow
A11 Tinted Glass
G50 Heavy Rear Springs
L47 400 CID V-8 engine
N40 Power Steering
Z53 Amp-Oil-Temp gauge
600 Black Vinyl Trim

I am not overly concerned at value of the truck...in fact, I could care less. I just want to see if there was that way of telling an exact date of production. Obviously narrowed it down to May of '72..
Truck was bought new, in Austin, TX from Henna Chevrolet, and guy I bought it from bought it @ 1996 with 20K original miles on it. So, I'm the third owner, and the 2nd owner went through the truck and made it a very nice truck. Repainted it, new interior. New ball joints, tie rods, shocks, brakes, master cylinder, rebuilt the rear end, added a 3.73 R&P and posi. Yanked motor, punched it .030 freshened it up, blah blah blah.
I am just wanting to find out as much info as I can on the truck.
Thanks guys
