Here is one of my many projects.
Recently bought a frankenstien 1956 Chevy 6400 V8 truck.

Currently has a 1972 350 V8.
Has some customer "slipper spring" on the rear, LOL.

Found out it has the firestone RH-5 rims, bummer.
Not sure what the final plan is yet.

Considering putting my D60/D80 from my '95 Ram/Cummins into it.

More pics to follow

Great looking Truck, but is cobbed up some.
Also a great way to unload it off the trailer!

I'm guessing it doesn't run judging by the wiring in the engine compartment.

Nice attachment for the exhaust pipe. wink

Is that an AD Big Bolt in the background of that one pic?

It runs, ran hot wire to dizzy off battery.

C-clamp on manifold is to hold a gasket in so it's quiet(er), passenger manifold has a hole in it I plugged with pig putty. No use spending lots of cash until I determine health and direction of project.

Guy I bought it from had a coe and a 1952, 4600.

Those are the original 265 exhaust manifolds (log type). If you decide to keep a SBC engine you should find a pair of Rams Horn manifolds and replace those...they restrict air flow.

How is the front of the rear leaf spring attached to the frame?

Mike,
All other spring mounts are good. I think someone broke a shackle or spring eye and did a farm built slipper conversion.

If I keep the sbc I was looking at center dump ram horns with generator mount. They are cheap now.

I was thinking that the slipper seems to have shortened the spring and raised the truck somewhat. Perhaps "they" were looking for "increased" load capacity...

Not having the leaf springs attached through the eye mount seems dangerous to me!

The shaft the leafs are attached to looks like a pair of axle shafts welded together in the center...

They are axle shafts.

Some trailer suspension designs use a free floating slipper spring similar to what this turned into. As long as the front is secure and the slipper end doesnt allow for much side to side play it should be ok. Slipper design ok, execution of this setup....less than desirable.

One problem with this is the frame has cracked where the shaft point loaded it.

Nice that it runs.
I totally understand about the C-clamp. Sounds like something I would do. thumbs_up

I think there is a U welded on under the spring to contain downward movement. Slippers are usually used to lower a vehicle or cheapen it as on a light weight trailer.

Pulled the rear suspension assembly today. Stripping the frame of all mounts, cleaning up previous alterations. Going to wire wheel and paint.

Installing a Dana 80 and lighter spring pack.

Had to drop the bucket to lift it off the ground!

Explains why I didn't have as much tounge weight on the trailer as I thought.

Since the originality of this truck is already gone I don't feel bad modifying it.
While the Dana 80 is lighter than what came out it is still plenty heavy enough. Also going to remove the HydroVac system. Not sure if I'm going with a firewall mount or complete under the floor system with a m/c for a disc/drum setup.

The 2nd gen ram I'm dismembering also has a gooseneck ball mount that I'll swap over too.
It's a '95 RCLB, Cummins/NV4500 3/4 4x4.

Make sure you maintain the same MC bore size when you plan your brake system, the power brake MC's available from all the vendors is to small for the big trucks...they don't move enough fluid.

It will have a brake system in line with modern 1 ton trucks.

The donor truck is a '95 Ram/Cummins.
First step is rear axle/springs.

The front is going to be...interesting.

I don't know how much that rear axle weights but it's more than a dressed 5.9L Cummins!

Just the rims and tires alone will be over 500 pounds and about 200 pounds wort of springs...adds up fast! The 5.9 should be in the 1000-1050 pound range...so, the rear wins! eeeek

Shortened the frame for a 10' flat bed.
Starting to mock up the Dana 80 and springs. These are 6" skyjacker springs that gave the Ram a 2-3" lift by replacing the factory lift blocks.

Cut the spring perches off the axle, frame narrower on old truck. Cleaned and painted all hangers from Dodge frame, leafs wider and longer. Moved axle about 4" forward from stock.

Nice job, on my '54 GMC 620, which is a heavier truck, it was easier to cut and splice the frame to shorten it 4'.

Update, using a radius arm kit with coilovers for the front.
Axle brackets are from ballistic fabrication, no complaints.
Radius arm kit, far from stock....quality control and customer service less than desirable. Upper shock mounts on the way from ballistic.

Steering needs to be sorted out yet, engine cross member has to be relocated for steering box.

TnDan those slipper springs you mentioned are overloads i think here in the corn belt...land of overloads...all the big trucks have em you put gun grease on so they can slide howeveri think GM aimed for leaf springs to stay dry thats what makes em strong especially when they re well arched !learned at the spring shop...fun place

In this case I was referring to the main leafs, not the overloads. The factory hangers and spring eye were cut off and turned into a slipper design using a axle shaft for frame "pad".
I grew up in the land of the "Michigan Specials", LOL.
