If time is a problem you can get back together on Monday (temporary at least) by getting a piece of 1 3/16" cold rolled shafting, drill a hole in each end for a lynch pin. LS should have the item in stock somewhere, you just have to wait to get it to you, meanwhile you are still operating. Most pins like that are shafting stock anyway. I keep several common sizes on hand for such contingencies. If you have welding capability just weld a large washer on one end of the pin, wow you have a new one for a lot less than LS will want.
Curious, what happened that you need a pin that large? Hard to shear 1 3/16 stock?
