The 1111708 Delco was designed for the N62 Continental engine found in the little model G Tractor. Over time, the little G's Distributor would start to get a wobble in it and before you know it, the engine is running kinda lousy. Eating main shaft bushings seem to be a common problem with the G. Always check for excessive side to side play in the Distributor. We have an exchange unit or we can rebuild yours.  Your call. 
Core Charge- $150.
