Has anyone run into a problem with trying to get a correct coupler for a p/s gear box? Classic Ind. and NPD sell boxes with a 13/16 input shaft but the coupler they sell is 3/4. A box for a 77-79 seems to take a 3/4 coupler. Trying to get this resolved quickly as I need to get this car to have a headliner put in on Tues. Thanks Wes

Search out and call Lee Enterprises. They'll be able to figure out what you need, and will have it.

What box are you using???

I am using the box that came on the car, it has a 13/16 input. We ended up with another road trip to NPD and got another coupler of the same part number and it was an exact twin in appearance but slipped right on. Unbelievable, they had 30 in stock and we got one that was a little off. Thanks Guys.
