Hi Kragh and Jackie,
An update, I had DNO rebuild my Tiger C5 water pump, cost me $180 including shipping, turnaround was about 3 weeks. They are very easy to work with. I had them bead blast the housing and it looks great. Everything feels tight but since motor is not back in the car it has yet to pass the ultimate test. They have a rebuld kit and the seal installtion tool available if you want to do the rebuild yourself. Will continue to update!
