I see that the Jegs add notes that is a 1410 series joint - I ordered the same series recently (different vendor, I think it was listed as a 5-1410X, can't find the receipt now) and it worked perfectly; I'd guess the Jegs part would work. Critical joint dimensions were 4.188" OD and 1.188" cap dia. (This said, I remember reading somewhere that there were 2 different OEM Spicer joints used by the factory, so these numbers might not be the right for everyone
) Regards, Nate
