Measure axle overall lenght, spring perch position and angle, shock mounts. Then you will see what is different.
Spring perches and shock mounts can be cut off and new ones welded on, no big deal.
Bought a quality Knipex wire stripper. Paid 20$ more for Made in Germany, I prefer to pay more for stuff not made in China/Asia/India.
All units in metric/imperial mm2/AWG.
Check all hoses if they have a tiny hole or are brittle. The fuel could flow from the leak down and and drip from the valve.
If the fuel is coming out of the valve there is an internal leak or something like dirt is preventing the valve to fully close. Or the plastic parts of the valve could be...
This is a more budget friendly solution.

LMC has the 73 - 74 cluster.
If you want to add gauges or tach you can use later cluster backing plates.

The old speedometer from your cluster is a 81 up with the clip attached to the speedo with a screw on the bottom side of the cable input.
The clips for pre 81 speedos are attached to the cluster backing plate with a screw on the top of the cable input. That's the reason why the 79-80 speedo does...

There are extrem durable powdercoatings available, stronger than bedliner. They get scratches but don't chip. When you blast the steel cap before coating it's nearly indistructable except you set your truck on fire.
I 've never seen black plastic tailgate caps, the vinyl protector is the only one in black.

LMC has stainless and diamond plate ones and vinyl ones with 3m tape.
