VIN Plate Decoding

[JefeAZ]

Was able to answer a lot of my questions already using BroncOhios decoder: http://www.broncohio.com/tech/ebvins.html

After clicking on 1974 at the bottom, I found that mine came with a 92" wheelbase, color is Medium Light Metallic Green, and a 302 with the C4 Auto(still in the Bronco just rebuilt).

What I cant find is why mine says U151 under Type/GVW when the decoder says U150 or U152. Also says 04500 on the bottom left by GVW but the decoder says 4700 or 3900. Body is 34, axle is B90. Bottom right of the tag says 57 and its cut off. I'm assuming that's the DSO code.

If the interior and exterior is not stock, is it possible to find out if its a Sport/Ranger or just a regular Bronco without giving Ford $17?

Any help is appreciated.

U151=4500 lb GVWR
34=parchment front buckets and rear seat
B9=3.50 gears 3300Lb axle (11" brakes, big bearing) w/Trac-Lock
0 is really Q=limited slip front axle and power steering
57=Houston

Vinyl inner door panels and argent colored grill opening=Sport
Metal inner door panels=base Bronco

I sent an update to BroncOhio for the '74 models 3 or 4 years ago. Never got posted.

Its been repainted at least twice and it has stainless aftermarket door panels. I may go back to some variation of the stock color. Appreciate it! More base Bronco's than Sports in 74?
