Getting my 84 silverado C-10 back on the road

[Schultze09]

Hi all,
I've been lurking on here for quite some time and now its time for my first post. This truck was purchased new in Houston by my father in 1984. We then moved shortly after that to Phoenix where he passed nearly 15 years ago. I got the truck and drove it for a few years then I moved to Minneapolis. I drove it around for awhile in the summers and parked it in the winters. About 10 years ago I just parked it and its been setting ever since. It has 70,000 miles and the body is completely rust free. AZ took its toll on the dash, seats and headliner. Well its time to get it going and have some fun with her again.

Things that need / should be done prior to trying to start it:
This is where I will need help from the GM truck guru's on here
1) buy a battery
2) change the oil
3) replace belts and hoses
4) remove gas and replace with new
5) ?
6) ?
You get the idea.
I have it in a nice heated shop with plenty of space to work on it.
I hope the pictures work, bad shots due to space limitations.

Thanks in advance.

Steve
