This week's developments so far...
(He currently has the cab blocked up on wood 3" from the frame to clean and strip /remove unnecessary lines and cobbled wires.
The truck had NO engine/trans/tcase/trans crossmember when he got it.)
We placed a bare 787 series 3.8 Buick block and factory Buick G-Body mounts into the bay.
It does look like we have a future interference issue w/ the right bank cylinder head & Valve cover and the AC box on the firewall, especially if he just goes w/ stock body mount or 1.5" body lift like he wanted (with a 2" suspension lift.) I still am un-burying the oil pan and the valve covers for this block from a corner of the storage area- so I'll have them to add to the block for mock-up soon.
It would help if I had/could find a factory correct reference measurement from the Block /Trans mounting face (plane) to a fixed point on the frame or the front axle centerline.
I have included pictures without the block being placed in any specific orientation/squared, etc.IMG_4309.jpgIMG_4308.jpgIMG_4307 (1).jpg

Also working on interior trim- wrapping w/ foam and flexible Pleather...Pics to come

Update:
Found out that the 3M77 adhesive did not hold in the heat on the dash filler, so he Bought 3M90 adhesive to re-shoot.

Progress so far:
Picked up a Chevy K2500 NV3500/NP241C 5 speed & manual transfer case
Was gifted an unused Buick 231 Centerforce Flywheel
Picked up an unrusted but dinged left front fender
Found & purchased an unused 3" body lift kit
Purchased NEW Skyjacker Softride 2" lift coils for the front
Purchased small right wheel arch patch panel and larger left rear wheel arch patch panel for the bed. Purchased sound deadener for the cab floor and roof panel
Salvage purchased factory jack and handle to replace the missing ones & a smooth straight '84 hood.
Got NOS front valence turn signal lenses and a taillight from our same local yard, cheap.
Got new LMC Weatherstripping kit for the cab.

Disconnected the cab from the frame.

Reached out to Bilstein for front shock options to match the B8 5100's available for the 2-3" lift in the rear.

Headed tomorrow morning early to the u-pull-it for first Gen Explorer Sport Trac rear leafs (may provide 2-4" lift) to replace the 'flat' rear leafs (looking to maybe eliminate the stock rear lift blocks to keep it almost level when empty) ; Evaporator and Condenser cores & stock 1st/2nd gen 4x4 Transmission/tcase crossmember

He's cleanned, rust converted, & painted the rear frame & underside of the bed floor. Pulled the cobbled wiring and rusted brake lines.
Cleaning and scraping the front of the frame to rust encapsulate and paint.

He's currently headed to Philmont High Adventure Scout Reservation with his fellow scouts for a week of hiking in the high altitude NM desert. Dad has a large to-do list in the heat in the driveway this week!

Progress so far:
I picked up a pair of 2002 Explorer Sport Trac rear leaf springs; got the Chevy 4x4 floor shifter assembly, linkage, lever & trim, proper yoke & tailhousing for the NP241C from a 98 Chevy K2500; Trans crossmember from a '93 Ranger 4x4 SC and the same rebuilt rear 2-piece driveshaft w/ new greaseable universals installed front to back and the new carrier bearing; Bed rail caps (aluminum diamond tread he will blackout).

I ordered PROTHANE bushings for the rear springs, radius arms and the bodymounts, which should be here between tomorrow and Tuesday.

Only things he'll need to collect on his return are the AC parts for the Ranger cab.

He's got his paint, interior materials, LED lights, seats, etc.

We just have to title the truck (once i reinstall the rear diff) and we can Let the build begin!
Work starts again today!

i have been running the top rating 2wd TIB 150 rear springs with offset slugs the last 10 years or so for general use. they work a bit better then the explorer units all around. the un laden ride is much better.

its simple to make a relocater shim...there is an inch or so difference in pin offset.... they tend to be the cheapest option new at that, so its not a bad deal and worth the hassel to me.. though last i looked the 1850's with 8 5/8 arch for 90 bux are long gone....they are about 150 each now.


at least your making progress....

i wish i could work on my truck.... someday...

Thanks for the input, BobbyWalter!
We got the springs for $80 total and new bushings on the way.
I'm working on this in the stone driveway with limited shop equipment, so bolt in simple is good for me.

I understand the someday...I wish I could work on the 87 Grand National hibernating in my garage for the past 14 years, but kids and tuition come first. Guess I'm saving that for retirement in about 6 years.

Currently the chassis is almost completely reassembled- just waiting for front bearings and front axle hub seals to arrive. I am having one nagging issue: I've tried twice to get these 10"x2.5" brake shoes for the stock Ranger 7.5 rear: (ACDelco RIVETED rear 10" brake shoes (part # 17581R was part #14581R). I'm trying to avoid the no-name bonded brake shoes & was looking for long-established names like Bendix/Raybestos/ACDelco, etc with few options. The online description (Amazon & CarID ) and photos show correctly, but both orders have sent Bonded brakes in the box for that #. ACDelco has some issues in their online listings w/ photos and listings matching BONDED versus RIVETED for the 5 brakes they show available for the Ranger, and Delco customer service informed me the set I have labeled made in China hasn't bee produced there since at least 2019. According to them only the dealers can get this part...So I have my local Chevy dealer ordering them from MEMPHIS for me for Wednesday.

Progress continues- Prothane bushings added F/R, Bilstein 5100 shocks in, new spicer ujoints, still trying to figure out the R. driveshaft and engine/trans/tcase placement - do I use the1330 Chevy one piece (too long for my liking), the 93 Ranger 2 piece w/ carrier bearing (shorten the short shaft), or use a double carden joint just behind the TCase (which seems to droop too much for my liking....)

Body's back on w/Prothane bushings & 1" body lift installed, Body primed but bed bondo & cab putty work not finished.
Stubby 2 piece driveshaft installed.

We hit a small challenge-the stock oil pan has some clearance issues as we had it mocked up, as it is a center sump and it locates directly above the rear TTB bracket and the engine crossmember. Going to have to play around with changes to the carrier bearing crossmember, motor mounts & the trans mount and trans crossmember.

Had a setback on the engine- the cam journal bearings in the 85 block were not viable, and the rod bearings showed wear. Refreshing the 85 shortblock soon. Pictures below...
