PB Booster Bracket Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bought a used power brake set up for my C10 2wd suburban for the brackets push rod etc, It was from a C20 and had a double diaphragm booster. I replaced it with a new booster that is listed for a 70 C10 burb which is a 10 3/4" single diaphram. To me, it appears that the MC will be lower in the front than rear. I have it up on jack stands right now but it doesn't look right to me. Are the C20 brackets for a dual diaphragm different. They can go on only one way and the booster is positioned with the check valve where it should be. Any ideas?
