need help finding parts
Now is not a good time to make decisions of this magnitude. I would suggest putting the truck in storage for now, and postponing any work for several months, or even a year.
From your questions, I am assuming you are not wealthy and have very little automotive knowledge. To get this truck in shape to be a daily driver again is going to take a lot of time and money. When you get done, you are going to have a truck that is not worth very much money and due to poor gas mileage, is expensive to drive.
You are really describing a project truck that needs a ton of work. A great project for a father and son to work on together over a couple of years, but not a good project to tackle now. You really can't just replace the rods. You need to rebuild or replace the engine. The rust can be repaired, but it will be back. The springs can be replaced. Plus there are other issues that you don't know about yet, like transmission, brakes, cooling system, front end, and other rust eating away at it.
Unless your son is planning a career in automotive repair, his time would be better spent concentrating on getting an education and enjoying life. Unless he has a lot of previous experience and tools so he can do much of the work himself, your son could probably do a year of college for what you are going to spend on this truck. I just think a decision on doing this should be put off while you both have time to grieve and get settled into your new life.
Again I'm sorry for your loss.
Sincerely Frank
Very sorry to hear of your loss. I just wanted to second what Frank said--and he said it very well and, I believe, sincerely. I'v put a couple of project trucks together myself, and I'm always amazed to find out that my best estimates of the time required for the hundreds of little jobs invovled are always at least three times LESS than the amount of time I actually needed.
And I'm somewhat experienced, and have many of my own tools. I can't say it as eloguently as Frank did, but I'm sure he's correct in his advice. After a year or so, when things have settled down, and you're not rushing to get it on the road, it could also be significantly CHEAPER to restify, if you spend the intervening year chasing down some deals on parts.
You might also consider finding a whole donor truck, for the cost of the individual parts you will need. And you never know--sometimes the doners are in drivable shape, and you could license the doner/parts mobile (after a minor repair?) until it's project time. Then you'd have a daily-driver truck with which to cheaply transport truck part for the restoration of your husband's truck.
Also, you can sometimes find donor vehicles, parts and tools on this environmental site--for FREE: The Freecycle Network (Drill down by country/state/city and "post" for what you seek. Read the rules first, as there is a protocol to the form of the posts. Not hard, but the moderators will correct you if you do it wrong. Good bunch of people, generally.
Again, whatever you decide, I'm sure he'll be happy that you're honoring his legacy in this manner.
And welcome to the forum--some really great folks "up in here" (as the kids say).
