i got the tap at a place called freds nuts and bolts in casa grande az. you can probably find a nut & bolt supply house in the phone book. if you do decide to do this and can't find a tap, let me know. i'll get this one to you and you can mail it back when your finished. i don,t have a scanner to post a picture (sorry). did you see the picture that was in the post on the braces. i think it was 12-29 and posted by fred h.
