Whoa..thanks Denny...so I have to make a new tie rod if I want to use the modern tie rod ends on the 3600?

Doable I guess..got some machinist buddies who may help. What are the thread specifics on the 3/4? The left hand die may be interesting to find.

or I could go back to the original ends...I have a a complete extra 52 3600 front end with the old skool ball/socket

Is it worth the trouble to swap?
