Depending on where the break is located you may have more damaged parts. If the impact cracked the base of the cylinder and allowed it to pivot forward while the engine was running you may have a bent connecting rod and a damaged lower needle bearing. Have you removed and inspected the crank bearings yet?
The muffler ripped off and broke the mount ring.This caused a small crack in the cylinder.
Also one of the engine mounting lugs was broken off so I need to check the crank. But just turning it over it seems to be OK.
You should be able to buy just the rear case half that has the mount lugs on it.
