Window cranks

[dmjlambert]

I guess I'm in a cranky mood, sorry for the disposition and the pun. I took the old original window cranks off, which are pitted and missing the knob on the end. I went to Napa and bought new cranks. They look the same. I put them on, and they felt so wobbly and had a crappy fit and feel. They were fully engaged and the pin was holding them OK, but they were just crap. I took them off and immediately threw them away, and put the originals back on.

I am accustomed to new items being high quality from Napa, but I was surprised and disappointed this time. I should have taken them back, but I was frustrated and in a cranky mood, so I didn't. Do window cranks need to be NOS or come from a Chevy dealer to fit well? You see my truck in my profile picture/avatar, it is not fancied up, it is just a rusty old 69 CST/10, so I don't care if handles I get are shiny or perfect. I just need them to be functional. O'Reilly's and several other auto parts stores are much closer to me than the Chevy dealer, but I will make that journey if it's worth it for this part. Just wondering.
