I have a set of these pumps from Fred also. They didn't fit in my application. I have had them for 3 years now. I can snap a picture of them if someone is interested. I would be willing to sell them since I am not using them for my 540's. PM me if you want some pictures. Let me know

I actually found a snap shot of what I have. I had them mounted for about 15 minutes. Didn't have enough clearance to tighten them belt. So I mounted the original merc ones on teague brackets. These are some pictures. PM me and give me an offer if you are interested.
