OK, I know someone out there has an answer to my question. I am wanting to mount a Saginaw P series pump to my Yblock. Bought the borgeson bracket from Summit and have spent days trying to get an answer from Borgeson as to why it doesn't fit/ line up. Finally they say it was never intended for a 272, only 292 and 312. Anyone have any similar experience?? Yes, I know Mummerts site has an expensive one, but I can't get any response from them when inquiring about which pump they use. No one has ever responded. ANY IDEAS out there?? Or do I just use the Borgeson as an expensive pattern??
