Wow, check this out.. BIG truck

[jarheadk5]

If he is positive it has 5.13 gears it most definately is not rockwell axles, those only come in the 6.72 flavor.

Prolly has the military duece closed knuckle front axle.
Cool lookin rig though.

There are other Rockwell rear axles, other than the toploader "deuce-and-a-half military", with numerous ratios available. I assumed Quaddawg was referring to the rear axle when I first responded, since I didn't read the eBay ad completely where it says the truck is a Napco ocnversion.
