Rack and pinion

Hello everyone. I'm new to the modify of the mopar A body suspension system. Has anybody here installed a rack and pinion on their A body? What's the pro's and con's of doing this? I was thinking about converting to a rack and pinion for the better handling and header fitment. Any particular brand preferred over another, cost? Car is a 1972 scamp with a 318 and a 904 transmission.

Here in Australia it is very common and works a treat. There are two systems available both behind the K frame.
