I bought one at a swap meet and put it on my 340 dart with no problems. Also put one on the 68 GTX that we have and may put one on my A12.

Its by far the best way to go if your driving one often. They take far less power to turn, are lighter and easier to install, better exhaust clearance, etc. Just a bit more $$.

I actually used the one off my 97 dodge 1500 after having it rebuilt on the GTX.

They made 100's of thousands, so if you watch, you can find a good one cheap.
