Hello dads06harley. I suggest you read this entire thread, and you will find most of the answers you're looking for. Also, use the search feature that this forum has, and you'll find even more info. Once you have a pretty good understanding of what's involved with the project you're considering you'll need to either start on it or throw in the towel if it's too much for you to handle.
If you do decide to start on the project and you need help with something then post a brief, detailed question (pictures are good too) of what you need help with. You're more likely to get replies to a post like that than a very long post containing a dozen questions.
I wish you the best. Just remember, the search function will answer most questions. When you've searched and searched and it doesn't then ask one at a time. There's enough info about fat tire bikes on here already to give you a very good idea of what's involved.
