Those of you guys that are looking for the plastic lockout knobs. I know they were discontinued a long time ago. I found a guy in Columbus, Oh. that has 10 of them at $14. each plus shipping. The place is Driveline 1 phone# 1-614-279-7734 Spicer part# 620102-1 I had bought some back in 2002 and I found the receipt with his phone#.
