Update 9/24/19
Well ... it's been over a year since my last M152 update. Much has been done, learned and redone. After 1.5 years of trying, the origiinal, running 251 engine finally sold on eBay for $500 complete with clutch and transmission. Other items sold like axles, wheels, Southwind heater (believe it or not) and cabin ducts.
The custom front Dana 60 axle build turned into a 10 month nightmare involving two different, "highly recommended" local Phoenix shops. Instead of shortening the Dana 60 housing the instructed 3-1/8", they lopped off 4-5/8" making the housing unusable. Had to deal with the BBB, but did get all my money back. Bought another 4.10 Dana 60 off eBay and have it under the truck so I can now finally install the engine. After witnessing these boneheads, I will be shortening the axle myself when the truck is near completion. So much for out-sourcing to save time ... LOL! 10 month waste.
Worked on the dash - 9 new Autometer gauges - looks fantastic. Had to widen the dashboard cut to fit. Installed the Southern Air Mini-Kool and Gobi heater - looks great. The exposed, metal Gobi will be painted olive drab. That Mini-Kool blows hard - 13' easy. The center duct blows into the camper box and hits the back door. Had to relocate the cowl vent actuator a bit towards the passenger side - got that working clickity-click smooth.
27" wide dually rear tubs made from NOS M37 fenders. Getting ready to make the cab cuts and install the tubs with body welting. Will look awesome.
Large roof rack finally in position. My roommate, Larry, surprised me with the heavy rack installed on top of the truck after I came home from a vacation. I thought it would take 4 people to lift - he figured out how to do it by himself! Now, we can raise and lower the rack for powder coat, etc. The rack floor is greenhouse decking - UV proof plastic, light and sturdy. I can sleep up there under the stars, if desired. Folding steps on each side of the rear door. Designed the rack's expanded metal sides to mimic the window grids below. Storage space is at a premium, so have several, wooden, Korean war era, military crates to populate the rack. Authentic Nathan K3LA train horn is on a real quilling valve and stupid loud. It's on a 1.5 gallon air tank, so can't get too creative - which is probably a good thing. 12v ATV winch in rear of rack will aid my aging bones raising and lowering the heavy, bifold rear deck/motorcycle ramp. Want the truck single person capable.
Many more things are in the works. Electrical diagrams finished. Have many parts, need to order more. All new wiring, panel, weatherpak connectors, etc. Almost everything will be LED. Looking at several options for power steering. Getting ready to install the turbo diesel. Debating whether to switch to a 700R4 automatic and 208 transfer instead of the manual NV4500 and divorced 205 transfer. Install would be easier with less cross-members and drive shafts. Over Memorial Day, We took Larry's 1951 Willys pickup to Moab and literally beat the crap out of it. He has a 700R4/208 combo and I was super-impressed. More responsive than the 4L80E in my Willys truck. It easily conquered everything demanded of it and shifted each gear selection RIGHT NOW - has no computer to think about the shift like on mine. I'm no spring chicken and may feel better with the 700R4 since this truck will be subjected to high mileage - all 4 corners and Alaska or bust. The hard part is the Isuzu to GM trans adapter. More study = more time.
The build is taking longer than expected because of many unplanned interruptions. Cold water pipe break taking out two rooms of my house, mold removal, insurance claim, walls, bathroom and bedroom reconstruction. Ouch - left rotator cuff surgery, recovery. Volunteering more time with Saint Vincent de Paul, etc. The deal is, stay the course, never compromise attention to detail and I will cherish this extremely capable and fun truck forever.
