The holes are complete. Notice another cut out to the left. This will allow the coolant hoses to be routed from the V8. This in no way weakens the car since the hole was reinforced from the wheelwell side. An electric water pump can be used, eliminating the large hole, but at the time of this build, I have not found one reliable enough. Also note the unibody has a rail that must be cut and bend down for clearance.
