Leaf springs

Well that's good to know. Is sanding and rust converter a good spring job or am Ibwasting time underneath the vehicle?

Answered more simply, if the springs are binding and the bumpy ride is sending you to the chiropractor, it's worth cleaning up those springs. If it rides like a Cadillac, you'd be wasting your time.

The springs up front are too stiff, the individual leaves are rather thick.

The shocks can be bad, even if they aren't leaking oil. I have found shocks in the past that were basically ornamental.

But the reality is that these trucks won't ever ride awesome without a huge amount of work and money, but they can ride better.
 
Keep in mind these are old vehicles and need tending to more so than 2018 rav4 or whatever ... more or less.
 
Does this work?

The last owner took a fuel injected motor and rebuilt it as carborated. Not sure if that affects anything.

You probably still have the stock TBI tank in your truck. The tank is externally the same, but fuel injected trucks had a baffle inside so sloshing fuel won't cause the pump to suck air. Carburetors don't care about momentary air bubbles in the fuel line, but there's no downside to running a baffled tank. You probably have a different fuel pump with a lower pressure rating, but some folks just put pressure regulators on the stock pump. Something to keep in mind if you want to replace the pump. Assuming the pump is still inside your tank, it's a good idea to write down the part number before putting the system back together. Just so you don't wind up buying the wrong pump later down the line.

Great advice about the pump? So that fuel tank in the link is what I need?

I will buy that fuel tank and switch it out. Seems like a pretty straightforward job. Any special precautions with the pump?
 
Looks like you have 3-4 inch lift up front and a four inch block on the rear with stock springs. The springs look ok but the rear block I’ve never liked. I had a axle spit them out and luckily I caught it before my axle fell off the spring perch. Looks like you could get away with rear springs for now. Maybe replace the front later if it rides really rough. Billstein 5100 shocks all around will help.
