can someone identify this water pump?

I have this waterpump that is lighter and less deep than the stock 89-91 model.

What makes it lighter is the aluminum versus steel front housing.

It also has no provision for the thermostat.

here are some pictures.

light one on the left stock on the right.

and on the last picture I laid the stock seal over the light pump, as you can see there is one mounting hole less in the light pump.

The light pump overall has a cleaner flow inside. The pump impeller is 1/4" different in size.

 

thank you.
