WOO HOO! My Cummins swap is officially underway!

Any updates? I'd love to swap one into my '84 Crew!

I've done the swap. I had an 84 Crew Cab single wheel one ton. You will have to use the core support from the 91.5 you got from the donor. I bought a brand new grill for the 92-93. I still have an NOS one in the box for a spare. I used the gauges and all the wiring from my donor 91.5. You have to move the wiring bulkhead over about 1" to put in the clutch master if I remember correctly. Other than that it is simple. Here is my one truck. It served me well for ten years. Sold it in 2012 when I bought a new one. The only bad part is the air conditioning is just not up to par for a big cab. Good luck. I sold mine for $6500.

You don't Have to use the 91-93 setup. Fastback66 used a 79/80 setup. Had to cut the core support to clearance for stuff and the lower valance. I'd rather make the 70s grill work instead of using the 91-93 like everyone else seems to. Plus 91-93 is my least fave. Get a Rusty support to cut for mock up and a pattern. Could also try to modify the 91.5 to accept the early headlight buckets. Food for thought.

My buddies and I have built 3 of these cummins trucks. Yes the 78 grille will fit. On my own truck I used the 92 diesel rad support and swapped in the 72-76's headlight mount sections. I also had to swap in the 72-78 hood latch but you won't need to if you just use the 92 hood.
These swaps work really well. I've been driving mine for many years.

My ecstasy at the beginning of this project has been replaced by a ho-hum feeling. It is moving forward, albeit at a snail's pace. Life got in the way a bit for the guy working on it. I'm patient, and I'm still overseas. I knew it would be a slow process, so I'm not too alarmed. A little anxious, though. At least he got the bale spike bed off the donor.

For what its worth, I like the paint scheme on the truck currently. But I gravitate to the 70's 80's style paint jobs.

Even better would be the large, and heavy metalflake.

I don't mind some paint from that era. I was young and impressionable during that time. But I draw the line at what I consider to be um... feminine colors. This is metallic, but not with flakes like a bass boat.

Oh yeah, I just bought a Borgeson shaft from Ignoble in the classifieds. It was too good of a deal to pass up.

Jees Louise! It's been a little over 13 months since I originally posted this thread. What's happened in that time? Not much. The guy doing the work got a divorce and had to move outside of town. The good news is that he now has several acres, a shop, and no close neighbors. The bad news is that his ex drug him through the ringer with back-n-forth court visits before they finally settled their differences. However, I have used the time to accumulate some good parts:

The Borgeson shaft mentioned above
A full set of custom Auto Meter gauges
A brand-new NV4500 with the 5th gear fix and cast iron tailhousing
An Advance Adapters swap kit
All new Anchor Industries engine and trans mount bushings
ARP flywheel bolts
And the Valair clutch and flywheel I just ordered this morning.

I know it's not a lot, but I'm on a budget, and at least I'm getting the transmission taken care of. He and I also agreed to swap diffs. He's looking for 4.10s, and my donor has them. Conversely, he has 3.54s under his dually crew cab, which I've been looking for. Can you say free gear swap?

BTW, he's keeping the bumper. Oh well, the uprights are in front of the turn signals in the grille, so he'll have to swap stuff around to use it. If you've read into what I've said so far, yes, he has a 78 crew cab dually, too, and it's the most recent Cummins 4x4 swap he's done. The more, the merrier! This one is his. It's actually an 84 cab, but all of the red and silver panels are from a 78. I had to remove some personal info from the pic, hence the gray rectangle.

Did the steering shaft you got have the universal or rag joint on it? Some have had problems with the universal joint shaft separating.

That orange looks familiar.....
We built Frankenstein a few years back...
Cummins, NV4500, Dana 61-70....

That's nice. My buddy has a nice rustfree crewcab dually 2WD and a Cummins donor truck. I'd buy it but I just don't need a crewcab.

What are your plans for the 2wd front end? I have a single wheel truck I'd like to convert

The front wheel adapters? Honestly, I figured they'd go to the scrapyard and become Chinese goods. If you're interested, they'll eventually be available, but I have no idea when. At least they won't be too far away, only about 360 miles. I'll make a note that you want them and drop you a line when they come off.

Thank you
