Anyone ever seen one of these before?

[rare86]

Thanks again for the Welcome.
Here is a rundown of the of the numbers of trucks that I know of and have pictures of:

20 1/2 tons extended cabs
1-83, 2-84s, 13-85s, 2- 86s, and 2-87s.

The two 86s are GMCs, the rest are Chevy.

5- 1/2 ton 4x4's, all 85s

3-3/4 ton 2wds

4-3/4 ton 4wds

2 extended cab one ton duallies ( i know the cabs are original to the mid 80s conversions by CVI, but cant confirm the bed is correct)

8- extended crewcab duallies.
4 have the pickup bed, and 4 have the Western hauler bed.

In all, I have found less than 50 in all, and that is including 1 extended crewcab and one extended cab that I know are scrap metal. Ive been looking for 3 years. One shows up every once in a while, but mostly I get repeats. Everyone keep your eyes open, and by all means, take some pictures, and get some numbers if you can. Thanks.
