I'm in the market for a PRW crank pulley....I have been reading and hearing of "defective" machining on the pulley where it mounts onto the crankshaft snout

My questions are....was there a time frame when all this happened? Was this mainly from one single vendor? Has the issue been corrected?

I don't want to be in the middle of this job and find out that I cannot get the PRW pulley back on the crankshaft
