Is this a non A/C power steering bracket set that will work on a 70 455? Someone is interested in buying it and I can't tell him the definitive application. I thought the brackets were basically the same from 68-72 but don't know for sure.

 

 

I'm pretty sure this is an A/C pump. There are provisions to mount the alternator bracket on top

 

The first picture you posted are the same brackets I have on my 70 455 that had AC.

 

The 1968-70 PS pump brackets are the same P/N for A/C and non-A/C, BBO and SBO. The photo in Post #3 is a 307 PS pump bracket, as evidenced by the fitting on the lower alternator bracket that accepts a long bolt for tensioning the alternator belt.

(Wouldn't it have been nice if Olds had incorporated such a feature into the PS pump bracket...)
