A journey like this makes you stand back and smile for a long time when its finished. I spent 7 years on a 37 back in the 90's and 6 years on a panel. yes it can be done and there is a lot of satisfaction that YOU did it and not just someone who just writes checks. As Kevin says, we are all here to help. I've been around here since late 90's and its a fantastic group.
....that being say, you may want to look around for another cab. They all will probably need work but you can lessen the pain just a little. Keep check in the swap meets for parts for sale and parts wanted. You will be surprised what comes up from time to time....just check every day.
