I'm rebuilding my 1955 TO35. The head is in the shop for a valve job. As I mentioned in an earlier post on cleaning up the rocker assembly and a missing pin that holds the shaft in place. To make a long story short, it looks like the pin was sheared off and made its way to the oil passage on a 7L rocker. All the other rockers are good, the 4 mountings are fine but this arm is bad and I made it worse. My hope is that I can find a single 7L that someone may want to part with. I don't really want to buy a complete assembly if I don't have to. Any help would be appreciated. Thanks in advance.
 
Bill, try Rocker Arms Unlimited in California. (Just Google the name.)
They rebuilt my TO-20 rocker assembly, including replacing a cracked rocker arm stand/mount, so I'd bet that they have individual arms.
Also, did you try a Google search on the part number for the 7L arm? That often turns up a hit on P*rts D*pot, or one of the similar parts broker websites.

Worse scenario...that arm is still available new from Agco. Part number 1750066V91 for the left rocker.http://www.jackssmallengines.com/jacks-parts-lookup/part/1750066v91
 
If no one comes up with a good used one, be aware the new one might come without a bushing, and if it has a bushing or you buy a new bushing, it most likely will need to be reamed to size.

They might ream it for you, but will need a micrometer measurement of the shaft. Measure where it is not worn or you can't get it on.
