Sean, I am sorely tempted. I think yours with the added parts could be made into a beautiful FJ25. But I am so far behind on my other projects it wouldn't be fair to leave it sitting for another decade while I putter and procrastinate finishing what I started. Honestly, I'm only now feeling comfortable with getting my head around the pickup trucks and their idiosyncracies to start down the path to fully understand the 25 series--I wouldn't want to botch the job on something so hard to find. I can see the pride you've put into gathering unicorn parts for what looks to be a well preserved core vehicle.
The other temptation of course is to buy showcases and exhibit the various unobtainium to probably my own singular observations. Believe me, I have enough of that disease already. Your truck needs to go to someone who really appreciates it for its rarity and wants to spend the time to create something worth putting on display and only driving in good weather.
Hang in there. That special buyer is out there. I'm sure guys here are toying with the idea, while some either haven't come across your post yet, or are arguing with the wife as to why another old car is more important than remodeling the kitchen !
Heck, we already know it's more important, but most of us know who's the boss !
Really hoping someone on here grabs it and then documents the restoration for all of us to see.
