Can anyone tell me what size and length of bolts holds the power steering pump bracket on the block of a 305? I've done tons of searching but can't find this specific detail. The original pump was taken off by the prior owner and I don't know what he did with the bolts. I have a new pump but can't put it on until I find out the correct size bolts to use. If anyone can point me in the right direction it would be greatly appreciated.

 

usually in these situations i just go to a junkyard and take the bolts off a another truck. id hate to get the wrong info from someone and also there can be different bracketry
