Don't waste your time trying to straighten out an old bent frame or fighting getting your blower starter off the car once the motor is running. Treat yourself to this machined piece of art.
These frames will only fit the new type RCD blower starters and not fit the older RCD, big C&A or Davis starters. A new added bonus on the frame it has been machined with a foot to hold the starter from rolling around when it is not in use and sitting on a flat surface.
Center hole is 4.125" and frame mounts to the starter with six 5/16" flat head bolts. Shouldered heat treated bolts lock the starter frame into the starter mount on the supercharger.
If unsure if this frame will fit your application check out #2050-0001A to make sure your starter looks like the one in the pictures.
