Mike,
Take Alvin's advice and call JC. My experiences with JC's has always been excellent. You might have to pay return shipping, but if you ordered the correct part number and they sent you the wrong part, they should send you the correct part and they should pay shipping.
Let us know how this proceeds (how it works out, we hope).
I have not had any problems with Jim Carter truck parts....they actually have been my exclusive supplier for this rebuild....hoping the part was mis-numbered and I got the opposite of what I ordered....it interfered with everything under the dash....
just wanna get this thing running and moving before the weather gets crazy around here...
