My sdp fit perfect and came with great directions, but I wish I would have done an all seasons kit and been able to delete the coil in the summer, but add it back in the winter. Truck starts fine, Just not quite as good as it use to....
Had one of the first EGR deletes from Scott @ SDPyears ago on my LBZ, fit great, and his have become better since then, as far as bracing the Y-bridge.
