I hate to say this, but I think you'll really regret it if you do not do crossover steering at this time. I wouldn't spend any money on front to back steering for a '60 unless road use is all you intend for it.
If you're using it on the road, wait and get crossover.
Otherwise, just do full hydro. Full hydro can be done for $200 or less if you find the parts in the right place.
I wish I'd just gone full hydro before I bought my crossover, I would have saved a bit of cash. I'm happy with my current crossover/hydro with 2" ram though.
