Here's what I did, First I ordered a chrome spacer from JP Cycles. I ordered the 1 1/4 inch that has a 3/8 inside diameter. Went to home depot and bought two of the 1/8 pipe that were 3 inches long and 8 nuts to fit. You'll find them in the light parts area. Placed the light housing in a vice and I used rubber to protect the housings but you could use wood or something. Used the two nuts tightened them together as a jam nut and used a 14mm to take the stems out of the housing. You have to cut the wires so leave room to splice them back together. Put one end of the pipe into the housing used thread lock and used two of the nuts as a jam setup. Put the spacer on and then did the same on the other end. If your going to go with the electrical connection set up to have brake and running light also this is the way to go because you'll have room to get all the wires through the shaft.
