Great looking truck. Welcome to the board
Do not "Bondo" the rust holes. You'll only be putting a band aid on it, and the rust will reappear shortly.
Take the time to cut out the bad, and weld in a patch, if you can't afford the replacement.
Since you're from Georgia, you're close to Lawrenceville, on the NE side of Atlanta. Year One, and Goodmark are right there. Both are real good people to deal with. Another great source of replacement parts are the vendors here on the forum, yet another source of parts and knowledge.
For advice? You have found the best source of information on 67-72 trucks available. Ask anything. BTW, don't get rid of your old seat. That frame looks in great shape. And it looks like Mother Nature has done half the work for you on the bed. Discard the rest and put in a wood one.
Again welcome to the board, and if you need anything, just ask.
