All 1*2 Alternator Pulleys The Same?

[Ads29]

Are all alternator pulleys the same?, I've bought a cup setup and being the clever arse that I am I've damaged the pulley on the cup alt. I've had a quick glance at my original alt that's still in the car and it looks similar but thought I'd check first incase I need to aquire another pulley, for reference mine has the plastic pulley on it

I believe not. I bought a replacement 2nd hand alternator for my 182 and the replacement had a plastic one, I put my metal one onto it. Everything seems fine, not sure if this was of any help though
