My 80 stepside

[Sweet Willy]

I have/had the same truck. I found an older style cab and swapped them out, changed the rear fenders, rims and tires, but, the running gear, etc. is all '80 and this is what I wound up with. I love the 80's model but I couldn't resist this resto-mod thing.
As far as your truck goes I'd keep the tool box, I might lower it a bit but other than that I'd just drive the snot out of it and go to a lot of shows and cruise-ins.
