I'd have to trash a good block myself, but I'd be happy to do some measuring and maybe send you enough dimensions to have a pump mount fabricated. Personally, I think it's a lot better idea to find a good block with the bracket still installed to build up, and let the one with the missing bracket go to scrap. Now if we were dealing with a 1902 Whizzmobile block or something else made of unobtanium, working with what's available would be necessary. 235's simply aren't that scarce. I was assuming you were trying to reinstall a part after somebody had a stupid attack and removed it.
