3B,
Gave Jim Carter's a call and I keep running into the same issue. Catalog shops know what is in their catalog. Truck shop in orange has 2, 10.4" units. One with a raised diaphragm and one that is flat. It seems with out the correct on in hand i can't replace it.
they list the 10" for V-8s only and not in my year at all. Classic was even less help. If anyone out there has hands on with this combo, 235/3 speed please help. Really would like to get this back on the road.
