This is a dual electric fan assembly from a 98-02 LS1 Camaro/Firebird the dimensions are 18"X26"X5".
The first thing i did was cut off all the un necessary mounting tabs and then cleaned the complete assembly.
With tabs removed & cleaned up.
I then fabed up 3ea mounting tabs out of .032 6061 T3 Aluminum for the top mounts and 2ea mounting tabs out of .040 6061 T3 Aluminum for the bottom.
Then i mounted it into the truck using the top of the radiator u channel for the top mounts and the rad core support for the bottom mounts.
