Grossie74, you are at a point most of us have experienced and some more than once. Being raised on a farm and remembering my grandfathers Studebaker and the AD style trucks I think I know where your coming from.
There are many ways to accomplish what you want....... the one thing you must have is patience as you decide. I feel safe to say that most of us here would say to get it to "go" and "Whoa" if possible and drive it a little and let it talk to you!!
Take your time in devising your plan so there is not much "backing up and punting".
There are some options to get the truck up to speeds for he suburbs and guys on here can lead you in that process. Take some time and read some of the tech tips and learn to do "searches" for lots of info.
Lastly, ask questions in the GARAGE FORUMS. Pick the one that you think fits your particular problem the best. You will have questions in probably all of the forums before your finished. Not everyone signs in and come through the Welcome Centre.....some read all the forums..... and some visit the forums they are most interested in. After a while you'll get the hang or it..... or the feel for what is going on. Visit the tech tips, gallery and links sections.
....and I may have mentioned this before, watch for bolters from your area and sign in at the forum for your area. Got to a cruise in often to help stay motivated and work on it at least 15 minutes EVERY day no matter how little or big the project is.
Good luck, we'll see you around the garage.
