heavy duty coil springs?

[cell]

Hey guys,

I am considering putting a cummins 4 cylinder diesel in my truck, but the beast weighs 750 pounds without accessories, flywheel, etc, so I need to know what my options are for beefy front coil springs.

How many different kinds of front coil springs were available for the 73-87 trucks? Were they different for 1/2 ton vs 3/4 ton? I have heard mention of heavy duty springs for use with a 454 V8, were these a special option?

For that matter, are the front suspension components (A-arms, etc) any different between 1/2 ton and 3/4 ton, or is the difference all in the rear?
