numbers matching? original engine?

NC John, Just for fun, I went and decoded the rest of your P-O-P

M0D28 is your transmission code/number
M = Muncie 3 speed
0 = 1970
D = April
28= 28th, April 28th 1970 Build date

DE0511K is your rear axel code/number
DE = TDE(T left off because in 1970 it's redundant) = C10 3:07 open
05 = May
11 = 11th, May 11th 1970 Build date
K = GM of Canada, assembly plant

R = carb code, Rochester

5 = Build month of the Truck, May

Chevy emblem = Manufacture, Chevrolet

Sold to:
Clyde Jones
Route 3
Mocksville, North Carolina
on September 17th 1970

Your transmission code/number will be stamped on your transmission
Your rear axle code/number will be stamped on your rear axle

On the redundancy of the T in your axle code. GM often did this on the P-O-P.
You should have TDE on the rear axle itself.

Thanks Bruce. I knew most of that of course but was surprised to see the transmission was a muncie instead of a saginaw like I thought it was.

Of course, that has been since changed to a T-56 and the 3.07 open diff is now a 4.56 eaton posi

Next time I am under the hind end I'll take a look at rear end casting numbers just for giggles (its still the original housing).
