My new 67 K10 - Anyone know who built me?

[tibado]

Be gentle, new user first post.

Just bought this off of Ebay a few months ago and am starting to go through it and 'correct' any issues, and was wondering if anyone on the board recognized it and may help finding the builder/restorer. I know the first owner was in WA, then it went to AZ to a broker in late 2014 then to the guy I bought it from in AZ this year.

What I know so far:
VIN = KE147Z126955
K = 4x4
E = V-8 Gasoline
1 = 1/2 Ton
4 = Pickup with Cab and Bed
7 = 1967
Z = Fremont California
126955 = Serial Number"

Engine - GM 350/290hp crate
Trans - SM420 4 speed with granny 1st gear
Transfer - Rockwell T221
Rear - 3:73 Gear

Some of the work I've already done:
1. Replaced the broken stereo with a Retrosound unit
2. Replaced the 750CFM (way to big and poorly adjusted) with a 600CFM
3. Replaced the Stock Engine X-Member with a DIY4x so I can get access to the oil pan without having to remove the engine... and upgrade to the round vs pancake motor mounts. Ill post the pics and process if anyone is interested.
4. Replaced the messed up front oil pan seal (see below) with a FelPro one piece dry seal, they thought it was the rear main causing all the oil leaks from the engine, its fine, looks like someone messed it up installing it.
5. Replaced the oil pan, valve cover and air cleaner
6. Replaced the Plugs and wires to move them to the top of the engine

Work in progress:
1. Replace the cracked intake that's leaking coolant into the block, this is the main reason they sold it, they thought the motor was going south. I found out that no damage had been done, luckily...
2. General cleaning, documenting and fluid changes in the trans, transfer, diff's etc...
3. Replace the right front wheel well, looks like a battery let loose and ate through front lower section. Its the ONLY issue with the whole body.
4. Find a good trans guy to pull it out and do a rebuild/re-seal to fix a minor leak.
5. Replace the worn trans, transfer, mounts and bushings, they look like they are all of the 48 years old and I cant figure out why with so much work put into the truck they didn't replace them all at the time they were doing the build...
