Probably not. 60/62 axles are wider, and FJ's have different frame widths than the trucks.
You'd need a new drag link and tie-rod at the minimum, but complete axles sell for alot more $ than ones with pieces missing, so leave the minitruck stuff complete, and get a new hi-steer kit, you'll come out ahead.
I dont know what the complete set of axles would be worth but id like to buy the front fj 60 axle if you are interested in selling it. If so please call 336 301 0550
