Not sure, Al. The Classic Parts book shows 2, possibly 3 that would fit my car with varying turn ratios. What I AM sure of is the Hedman Header is going to have to come out in order to get the steering assembly out. Won't come "up" through the engine compartment, won't come out from below either due to the header. That's OK, the header gasket could use a replacement.
