..... "testy over a door latch", you bet Les.
Just so everyone will know, I had a hard time with mine and took one over to my body man. Well, he got it apart alright but he royally messed it up. So, I took the other 3 and ran back to my shop. Laid them UNDER the work bench for a while and then found the thread above. After reading and getting the pictures firmly in my pea brain I tackled them like a hungry hound on a hambone! Man, they came out VERY nice. Yep, I'm testy about door hinges

And you better behave before I call the boss!
