Another Vin Decode Question

[Terkish]

I just have a few holes in my Vin decode for my new 1975 EB, I haven't been able to find the answers to. This is what I have so far. What I can't find I put in ????. Does anyone know what I'm missing means?

U15 = Wagon
G = V8 302
L = Michigan Plant
V88048 = Nov Built

WB, 092 = Wheelbase
Color, S = Midnight Blue Metallic
Type/G.V.W., U151 = 4600lb GVWR
Body, 34 = ????
Trans, G = C4 Automatic
Axle, 18J = ????
Max G.V.W. LBS, 04600 = GVW of 4600lb
1975 = Year 1975
76 = DSO: Denver

Thanks, Clint

Or if anything I have is wrong let me know.

I believe in 18J, J = Front Axle, Power Steering 2,500 pound and 18 = Rear axle 2,780 pound, 3.50 gears non locked. *edit: I should probably say "non limited slip" as I don't think any came with factory lockers. *edit 2: changed to 2,780. I forgot the 80. Thanks Okie4570

The body code has me stumped.

18=3.50 2780 Lb axle
J=Power Steering

I don't know all of the body codes.....viperwolf does though

34 is parchment vinyl front buckets with the rear seat.
