Need rebuild kit for yanmar 3GM pref US based
 

Finding alot of non 3gm kits online. What engines are identical to the 3GM? Read the 3YM is a direct replacement, however the motors im working on has integrated thrust washers in the rear main bearing like a sbc, the kits im seeing for 3yf have split thrust washers more like a perkins..

motor in question is a 3gm30 -

Thanks
