The Optima Red Top is the best battery I've ever used. I bought their maximum capacity model and have never been more pleased. Note however, that the battery cover can't be used as the battery is taller than the wimpy Ford unit. Note too, there is a small wire running to the battery from the firewall and it will probably have to be spliced and lengthed for it to reach. You may also have to reroute the battery cables some. On my car they barely reached. Maybe there is some way to lower the battery tray. That would be the optimal solution.
This battery holds a charge better and has no free-running electrolyte.
Once you try this battery you won't go back to conventional "maintenance-free" batteries.
