Found another site,same oem part but a little cheaper.This site is overseas and will take a long time to get/////https://www.ebay.com/p/1230307W00-Nissan-Pullycrank-Genuine-OEM-Par...
Yikes! I was hoping to source a used one. Mine might be OK. Previous owner had a weird thing about tightening ANY bolts on this thing.
What makes you think you need a new one?
The keywayis all torn up I was able to install it in the right spot but I'd like to have a good one.
Hey Karl,someone named Thomas Buckley just joined our site,he has a 84 parts truck,see if he will sell you the pulley.
Good lookin' out guy thanks
