leaf springs or coil springs?

[ryans69chevy]

I have a 49 chevy 3100 that needs a new rear end. I plan on getting one from a 63-70 chevy. Not sure what I should go with leaf springs or coil springs? Right now it has a 3/4 ton leaf spring rear end in it. But since I want to get it back to a 1/2 ton I could change it if I wanted. What's the benefits of either? What would be better to do? What's the easiest? Cheapest?

The truck is going to be kinda a weekend driver or whenever the weather is nice and for car shows.

Thanks!
