rack and pinion steering

I have a 65' small block coupe ( owned for 29 years) that has your typical play in the steering mechanism. I placed a new steering box in many years ago, I've seen advertisements for bolt-in rack and pinion set-up.; does any one have any experience with this modification ?

Go to www.vetteworksoline. Dan will help you out. He just got done installing R&P on his own 68. He sells the systems also. Tell him Craig sent you.
