Slant 6 power steering belt replacement

I'll just add a small data-point. I think there were 2 different p.s. pump bracket designs for the Federal pump in a slant-six. I say that because the OE bracket in my 1969 Dart cracked, between the 3 bolt holes to the block. I noticed that because the pump was wiggling too much. A junkyard bracket I pulled at a salvage yard was a bit different, so likely the designers had learned of the problem. I recall the OE bracket looked like the photo in post #5. The replacement bracket had vertical slots at the top that the cross-bolt dropped into. That was ca 1986 so don't fuss if a bit off. The replacement was likely from a car just before they changed to the Saginaw pump. No internet to learn then and I was a newbie, so probably lucky I pulled a bracket for the same p.s. pump since I didn't know they earlier used a similar-looking TRW pump (different brackets) and later the Saginaw (oblong reservoir).
