Hello to my all my fellow grease monkeys and technicians. I’ve got a quick question pertaining to front leaf spring bushings on a 2008 Kenworth T800 vin# 244577. I’m looking to change all 6 bushings, but I’d like to swap the original silent block rubber bushings for the greaseable threaded pin style. My local KW parts department is fairly helpless without a vin from a truck equipped with said threaded pins and bushings. I was hoping someone would be able to point me in the right direction with a OEM or aftermarket part number. I’ve searched Atro’s website with no definitive results. Thank you.
