I'm going through this now as well. I bought the Moog HD springs for my C10 because that's what the glove box sticker says it had originally. Bought them from Summit Racing. They will not clock correctly in the frame and lower control arm. It's either/or. Summit tech line says they are correct for the year and model. They gave me the tech line number for Moog. When I talked to them they said they've been selling that spring for these trucks for decades. When I told them the problem, they said to seat the spring correctly in the upper perch and not worry about perfect seating in the control arm, in order to allow the spring to twist. I think that sounds goofy, but that's their story. Regardless, the spring is in and can't get out of the control arm so I'm going with it.
