Race car Alt. Wiring? Steering box interchange issues.

So you've found the power and manual shafts are different sizes. You may also know the power steering column shaft is about 3 inches too short for a manual steering box. I'm pretty sure the aftermarket power to manual adapter will solve both issues. It fits the power steering box coupling and extends length to reach and fit the manual box. There are a few vendors with a wide range in pricing. Hope this helps.
