I did not, but noticed that the inside diameter of the copper tube is smaller than the steel tube that the mechanic used.  (about 5/32" for the steel compared to 1/8" for the copper - not exact measurements - I checked by trying drill bits until I found one that would fit in the tube)  What is the inside diameter of the stock nipple?
