Worked like a charm on my short pontiac water pump

Cheap, simple yet does what it’s supposed to. They are laser cut aluminum with the protective sheet still on one side. Measured 2.75” in OD and fit my 86-93 Mustang stock water pump pulley.

Shims assist with accomplishing perfect belt alignment. Very good results.

Had to redrill for fitment. After that they did the job.

These worked perfect on my 1980 Corvette. I used these for spacers when removing the smog pump pulley. My motor is a SBC. 350

Needed to shim the waterpump pulley on a 60s chevy inline 6, had to use all of them, with longer bolts, and lock washers. Works as intended.
