Power steering box on 74 duster 318

Don't cut the steering shaft!
If I were going Borgeson, I would go with the Bergman Auto Craft adapter.

I changed mine recently (74 Duster 318, p/s) but I went with the Firm Feel Stage II.
I like it, but I've got stock manifolds, not headers.

The Borgeson might add some room for the headers, but it will require a little bit more work.
FWIW
