If your truck isn't already equipped, here's a list of comfort options, to make your jewel even more enjoyable.
Power steering
Power brakes
Disc brake conversion
Air Conditioning (since you're in Cali)
Paint is your decision, as are any suspension mods.
Just think anything you're about to do all the way through, especially along the lines of drivability and cost.(don't put yourself in the poorhouse, or tear your truck apart, before you can afford your next mod)
You have an amazing truck there, enjoy it
