Small block water pumps

I think I am going to keep the 70-up style water pump and timing cover, I will try and see if I can get my radiator changed over...it sucks because it is a brand new BE COOL radiator. As far as the power steering I will have to bolt it up and see if it works, I may have to scrounge for 70 style mounts as well. I just hope it doesn't block the timing marks.
