Want to start my bag project. Need help.

[MacsGTO]

Ok guys I'm really reaching out here. I'm in the Navy and currently deployed. I'm saving up some moola to get my '65 the way I want her. I plan on starting the project when I get home and I don't know where to start. My internet ability is really limited and it's taken me almost an hour just to post this. I've done a few searches but it's so frustrating I've given up and turned here in hope. I currently have c-notches in the rear and converted the front to disc brakes from an 80's C-10. I really want to bag her out and z the frame to lay rails but that may have to be later. If I buy a set up now and do that later will I have to buy new parts? I also don't want to come home and just start ripping stuff off of the truck with not knowing what I'm doing. I want a solid bag system and want to tow a 25ft +/- boat. Is there a start here for newbies thread? I'm open to all advice and know I need to proceed with caution. I have some welding ability but I'm no pro. Thanks in advance for the help.
Very respectfully,
George
