Front anti-sway bar for my 1980

[Gigem]

My 1980 stepside did not come from the factory with an anti-sway bar installed, but from everything I have read on here it sounds like a good idea to install one.

Truck will remain stock ride height, not lowered at all.

Questions:

1. Is it worth it to buy the fat aftermarket bar, or is one from a junkyard with new bushings installed good enough? If aftermarket is preferred, which one is best and easiest install?

2. Will this be a bolt on deal, or are there holes to drill and/or welding to do?

Anyone have any good pictures to help me visualize what I need and where it goes?

Thanks!
