Mad Honk 

Friday afternoon and the work has begun again. I am skipping doing taxes for a day. This is version one with a drop distance of .8". The Stainless steel bolt will hold this piece in the bridge at the original brake bolt hole. The darker 6 X 1mm bolt is just a placeholder for where the SR brake bolt will attach. The two washers will go under the raised portion of the original bridge. One spacer washer with a star washer to hold the extender in place.

Side view of the extender. There should be more than enough material to hold the bridge stable in the frame.

other side view. Same applies to the material involved.
