Well it has been a long time since I posted any progress. I finally got around to modifying the shortbed to fit my highboy frame. I created a how-to thread in the body forum. Here is the link:

viewtopic.php?f=8&t=6448

See that thread for more detail, but for the sake of continuity I wanted to add some of the build progress to this thread.

Here is my makeshift gantry for testing the bed fitment.
Image

I moved the middle crossmember to match the highboy location.
Image

Image

I made a new crossmember because it felt like too big of an unsupported section and don't want the floor to bend.
Image

I made new holes in the bed for the narrow frame. I used sleeves and filed the holes square for carriage bolts to work. I welded the old holes closed.
Image

Image

Image

I made several standoffs to adjust the bed to the different frame contours
Image

Image

I fixed a few rust holes on the floor
Image

Image

Image

Image

Then finally I sprayed the underside with Zero Rust and the inside with EZ Liner.

Making progress is always nice. The bed really turned out nice!

Thanks guys. It's fun to share with this group.

Now that the shortbed is basically ready to mount I have been looking at the rear frame. I figured I should protect it while it's easy. Overall it is very solid and I'd like to keep it that way.

First I cut off the bump stops and braces since I will never bottom out and it's just a place for rust to grow.

Wire wheeled everything I could

IMG_20190822_58169.jpg

And 2 coats of Zero Rust. Ready for the bed now!

IMG_20190822_57670.jpg

In other exciting news I finally acquired a 78/79 HP Dana 60. I had some cash from selling my old shortbed and a good deal came up. They aren't very common here on the Island so I had to get on it. I currently have a closed knuckle drum brake 60 which sucks and getting the discs will be a big improvement. I need to go through all my brakes but don't want to put effort into that old axle. The HP 60 will help if I ever put a diesel in which is likely one day.

It seems in overall reasonable working shape. I need to add shock tabs and move 1 spring perch but that's no big deal. It was modified for a Chevy project then never used.

IMG_20190822_3677.jpg

It has 3.55 gears which I am really happy with. Most often they seem to be 4.10. My rear is a non-original Dana 70 with 3.73 gears but I plan to swap that out anyway, possibly for a Sterling with 3.55's. For a while it can be a 2wd only. The guy with the axle also had a rear Dana 80 for sale with matching gears from a 2002 Dodge with disc brakes and working drum rotor parking brakes for only a few hundred bucks. I'm still kind of thinking about that but have other priorities at the moment. I can likely get a Sterling 10.25 for a hundred bucks when I want to.

Today was a good day! Finally got the bed mounted and thankfully everything fit perfectly after my modifications that I risked not test fitting.

My bed lifting jig and makeshift gantry.

Fresh black underbelly. Stay away rust.

New carriage bolts look great

And here is the truck now.

Maybe soon I will quickly paint the bed black and fix a couple dents, but for the moment it looks great in all its rust free blue glory. :D

Also awesome news today I insured the truck for the first time in 3.5 years since owning it (not counting TOP's to move it). I woulda had it on the road tonight but I need new light bulbs and some wiring fixes to get the bed lights working. Maybe this weekend. I should be driving this thing in no time!

My 78/79 HP Dana 60 that I bought had 5.38 gears in it. I also need to add shock tabs to mine. I know I've seen them for sale before but don't remember where I've seen them. Because I'm being lazy and haven't looked into it lately, I'll ask where are you sourcing them from? Are generic ones from somewhere like Summit good enough or do they need to be application specific?

I haven't got into any of it yet, but it looks like there are a ton of universal ones easily available. Don't think OEM ones are available. If you do crossover steering or not it may affect where the shocks need to go. The shock mount on the spring pad from a 80/90's F350 would be easy but it won't work with push pull steering or I think the drag link would hit the shock.

I was not able to drive for a couple days after insuring the truck because it was taking longer than expected to get the rear lights working on the new shortbed. First it was the bulbs so I replaced them all, then it it turned out most of the sockets were bad too. Luckily the local wrecker had a parts truck and I got more sockets for cheap. I also snagged the tailgate pivot pieces I had noticed the shortbed was missing. Now I can get the tailgate mounted.

With the new sockets the lights were working after I wired it all up. I connected the bed lights using a trailer connector so next time the bed comes off it will be easy.

IMG_20190827_39984.jpg

The best part is that with the lights done I was able to drive to work today in the truck :D It went fine with no issues, only a growing list of little thing to care of. It drives well and the ride is surprisingly good. Here it is NOT in my driveway for once.

Nice! Being able to drive your rig instead of having it hold down the driveway is worth getting excited about!
