I have a 77 camaro with a small block.I bought moroso solid mounts that mount on the block,but the frame mounts are to wide for the block mounts to go over.The frame mounts are 4" across but the moroso mounts are less than 3".A friend gave me some stock steel mounts that are supposed to mount on the block and fit the frame mounts but I can only get one side to line up the other side is way off the bolt hole.Something has to give,can anyone help a dummy out?Shouyld I buy new moroso frame mounts?But why would the stock horseshoe block mounts not align with the stock frame mounts?Did GM make different block mounts for cars and trucks?Any help is greatly appreciated.
