Need VIN decode please

Hi,

I am looking at two newer trucks to purchase, but the docs I have on hand are only applicable to older ones such as the 2 I have currently.
If somebody could decode these two, I'd much appreciate it.

Cheers,
Tim

L90 = CT900 gas

L = 534 4v Super Duty gas V8

V - Kentucky Truck Plant

S34284 = 1973 numerical series, July 1973 production

153 = 153 inch wheelbase

G = Chrome Yellow

L900 = CT900 gas, 39,000 lbs GVWR

4A8
4A = Black Vinyl
8 = (with a numerical first digit) Standard Cab without sleeping compartment, Series 91A (Tilt cab. Cab and chassis vehicle)

No transmission code. This is a special order truck and the transmission was probably part of that order.

MFP
MF = Eaton model 34-DSE single speed rear axles, 34,000 lbs capacity, 7.17 ratio
P = Rockwell (Timken) model FF-903 front axle, 12,000 lbs capacity, with power steering.

39000 = 39,000 lbs GVWR

730407
73 = Salt Lake City District Sales Office
0407 = Special Order Number

SD engines are tough on gas and tough to shop for.

Is this a runner?

C80 = C800 gas

F = 391 4V HD FT gas V8. (Master Parts Catalog says "XD" for '75-'78. Shop manual says "HD" for 700-900 trucks in '77. Info on "XD" below)

V = Kentucky Truck Plant

Z06937 = 1977 numerical series, July 1977 production

153 = 153 inch wheelbase

JC
J = Rangoon Red
C = Special White (also called Pure White)

C807 = C800 gas, 25,100 lbs GVWR (Conflicts with GVWR on the plate, probably due to the special order)

118
11 = Standard Cab Trim-Bench, Blockweave and Crush Vinyl, LT Gray
8 = (with the numerical first digit) Standard Cab without sleeping compartment, Series 91A--tilt cab, cab and chassis vehicle

2 = Clark model 282V five speed direct transmission

FBP
FB = Eaton model 18221 two speed rear axle, 22,000 lbs capacity, 6.50 / 8.87 ratios
P = Rockwell (Timken) model FF-903 front axle, 12,000 lbs capacity with power steering

31000 = 31,000 lbs GVWR. This conflicts with the GVWR given for the model in the MPC and Shop Manual. It was probably due to the axle selections made for the special order--axles you would normally see under a 900 model based on the GVWRs shown for those.

581988
58 = Twin Cities District Sales Office
1988 = Special Order Number

Not yet :-) thanks for the decode, matches what I was told for the most part, so that's always a good feeling.

Cheers,
Tim
