1050A Loader Hydraulic Pump

I have a 154 Lo-Boy with a 1050A loader and tonight while I was removing the PTO driven pump to check the level of fluid in the transmission I discovered that one of the ears that the loader pump mounts to the tractor with is broken.

Looks like someone at some point in time tried to fix it with JB weld. While I have used JB weld before I am not sure if this is the place to use it and I am interested in finding a replacement pump. Does anybody know where I might find a replacement or does anybody know the specifications of the stock pump? Searching through the forums didn't yield too many results so any help would be appreciated.

Thanks

Pumps can be found at www.surpluscenter.com or at www.northern hydraulics.com. or search for the model number that's on the pump. If you disassemble the pump the broken ear can be welded I'm sure.
