Is teh 89-91 Auto counter weight part number : 0842-19-025?



That ist he closest thing that resembles a counter weight in the parts fische on page 1-K11

From the list of rebuild parts on Mazdamotorsports they call it:



N351-11-521



86-92 counterweight (they all use the same one? https://www.nopistons.com/forums/pub...1047683561.gif )





That number you have is called a backing plate of some kind and is less than $9. That's not it.

the act only comes with the flywheel. thats why the rb flywheels are price competative, cause they come with the flywheel and hardware
