Replacement for cross-threaded original

Fit my Fabricator perfectly. My complaint is with my original needle bar in my Fabricator. I have always had a problem inserting the needle. Even after carefully cleaning the opening in the needle bar and lubricating the head of needle shank, it has always been a problem. Being a former auto shop owner and doing many repairs myself, I am always very careful not to force or cross-thread anything. I accidentally backed the set screw out of the needle bar and absolutely could not get the set screw to thread back in. In my many attempts to reinsert the set screw, I must have cross-threaded the opening in the needle bar. The metal that the needle bar is made from would not allow me to use a 4mm tap to insert an oversized set screw. Hello $20 needle bar, thread guide, and set screw. I ordered all three to be sure all were new. After inserting the new needle bar with the thread guide and set screw all is working again. I had a week delay on the seat I was working on, but now it is completed.
