1969 Mustang Convertible rack & pinion?

[RussMS]

I am starting to look into rack & pinion options for the car. Is there anything I need to consider if I am going to be lowering the car in the future? I havent decided how I am going to get the stance I want out of it, but I dont want to limit my options if I can help it.

Also, anyone got recommendations for r&p systems they like or don't like?
