This... there is something I hate about having others tell me what to do with my truck. I don't really see any appeal in a "stock" old truck considering what I want...
If I got a stock 84 the first thing I would do would be drop the steering for a sag system. Then a Turbo. The second thing would be to figure out the best way to piss off the purists... perhaps a SOA or a more mild lift 4link rear (something not too high but comfortable to ride around town) Followed by new seats... prob the same BMW ones I have now.
Also considering the work to swap a 5spd + 3B into an FJ that's the route I'd go... if you buy them together its pretty simple.... It took me about 1 month to convert mine working weekends + nights after school. If I did it again I think I could do it much faster having already figured out the pieces.
I do see an appeal in pissing off purists though!
