Durinig the Christmas holiday I was able to get the center section temporarilly put together. I decided to go with the Crow harnesses and needed them to get the correct spacng for the hardware install. Vans has you drill the seat belt anchors to 1/4" and secure the factory belts with AN4 bolt. In order to have the latches of the Crows rotate freely I had to open them up to 5/16" and fab spacers out of bronze bushings. I cut them down to 3/16 in length, and the fit was perfect.
