I have a 261 to go in my 52 COE and need to do same thing on pump. You can get shorter pumps, but all have smaller diam pulleys.
On that good **** part list, try Obsolete Parts place, need to call, not on line. You'll need the part number, as only way to look up if they have.
Maybe that's Obsolete **** Parts, cant recall. You'll have to go to some **** place on web to get the number, not sure where mine is. Another place called "Greens" has old parts and uses others on a big link around country and can find one on other members lists. Lotsa Help, huh?
