$1,000.00 to put P.S. in my 67 Barracuda?

Do you have to still change the steering shaft if you use the Borgeson?
If you're doing all this work, you should also replace the rag joint with a real universal joint, which Borgeson can also supply. You don't need a different steering shaft, as all you need to do is shorten the original one. Borgeson supplies pretty decent instructions with their kits.
