s14 ka vs rb26 alt pulley

[noodl35]

Ok so while doing the quest alt upgrade, I accidentally dropped and bent the rb pulley. After close inspection of both ka and rb pulleys, they both seem to have the same diameter and rib design. Do you guys think i can use the ka pulley on the rb alternator?

why not use the quest pulley, works fine just one rib will not be used...

trick with the pulley is the backspacing, if backspacing and spline count is the same then yes they should be able to be used interchangeably.
