I looked through your pictures and you've done a really nice job on your truck. Restoration definitely is a money sink when you are in the middle of it, but looks like you've got most of the expense taken care of. In my opinion, most restorations bring less than people have into them, and if you could find one that is nicely done, money wise you are probably ahead to buy it completed. You are probably way ahead to buy one like yours, that is almost complete as typically many get where life gets in the way or it gets overwhelming to carry on. I however, enjoy the journey getting there. I think its great to bring something that didn't run back to life.
Following your thoughts, I share your frustration. I know its tough to keep going. But you look like you are really close to driving it down the road. I have a 72 Chevy 1/2 ton 4x4 that I started tearing apart more than a decade ago! We've moved 3x, had 3 kids and run two businesses-plus built and lived in construction zone since then. I have my days where I'd like to crush it! But Ive found if I work on it as I feel like it and don't guilt/force myself to, I'm happy with it. You know what works well for me?...I make a list of everything that needs to be done, then I don't over commit-every improvement is a victory that can be measured. My two cents-if your up to it, take it a day at a time and finish it! Down the road, as nice a job as you've done so far, you'll be glad you did. I think that's the real value of SS is you can network with people with common interests. How many people on the street do you meet that would even have a clue what a g749 is??! Looking forward to seeing your progress!
