GRANT- Can you confirm this is what you ordered? These are the parts I put together from mcmastercarr on PN, but want to make sure you didnt realize something was wrong.
Alrighty folks, here is a parts list from Mcmastercarrs website.
(You only need to order the threaded shaft from them, I got the heim joints and the jam nuts in both rt and lft thread from my local Orchard for about $12 compared to the $14 each listed below)
