I'm planning on replacing my dash with the nice one I have I posted about a year or two ago soon and while I'm at it, replacing the heater core and installing an OEM AM radio I have. Question - is this the only support bracket I need - assuming this is even correct - for a 1969 Ranchero? I clipped this image out of the 1969 service manual. It seems like there should be two of these brackets, not just one. Thanks.
