I bought the Auveco kit and was not exactly happy. The hole for the bushings had to be drilled out to 1/2" and the holes on the body side of the hinge (where the pins go thru without bushings) have to be drilled out to 3/8".
Add a couple of fresh $15 drill bits to the price of the job. If you have the "pilot point" type of bits, you won't be able to center them properly.
It's not really Auveco's fault - I think drilling is required no matter whose kit you get. Though maybe some others only need new holes for the bushings - I dunno.
Drilling the holes is an opportunity to get something out of round, out of line or wrong-sized. It would have been much faster to buy new hinges, and easier too. New hinges are not cheaper, but sometimes time is money. Like when you put off the PITA of rebuilding your hinges so long that you tear the latch out of the door. #@$%!
HTH a little
