Well guys just got done installing the Ruffstuff 1 ton tie rod on my 2012 sport. Just thought i would share with you guys that i DID infact have to drill out my knuckles and use the inserts for the TRE to fit correctly. At first we didnt drill them or try to ream them and it fit enough to use safety wire through the hole of the TRE to secure the castle nut. I wasnt happy with it so instead of buying an expensive reamer ( i know it was prolly the better way to do it though) , i used a 7/8 drill bit and went slow using cutting oil and it worked out great. for 135$ you cant beat it. Have fun modding my friends.
