Original Kilby OBA, first gen
Here are some pics of an original Kilby OBA for the first gens. I ordered this back in 93 when Kilby was a one man shop Calif. Not shown is the 2.5 gal airtank and regulator that came with the kit.
The only unique part is the combo drive pulley, everything else can be fabricated.
The only thing the kit did not come with is a oneway check valve at the tank. Once the air is turned off it's only a matter of an hour or so and the tank is empty.
The bracket bolts on the top and on the bottom of the mount to a bolt on the vacuum pump. The pump mount is nothing more than a L bracket.
Forget to mention that you have to move the oil filler from the front to a valve cover. The kit came with both.

I've had mine on my ramcharger since 2001. It was a life saver when I moved up to austin. We had 5 flats on the drive up and it was used to air up the tires on every one of them. I'de say it was possibly one of the best mods to my offroad truck ever.
