I'm installing an electric Meziere water pump on my 2005 silverado but the thermostat housing is not the same and the pump is missing a whole for one of the bolts on the tensioner pulley. I know these pumps are designed for F bodys but has some one done this swap and how did you do it?

 

you need to use a SBC Tstat and modify your Tstat housing so its hallow

 

here you go.
