The MJ Clamp might work good idea! Course there is no rush as I have 6 broken bolts to get removed.
When I went to Kenney's figuring the Cherokees would be similar but they aren't quite. My pipe is solid plastic with rubber physically attached at both ends (not overlapping and clamped but literally attached). I did grab one of the ones off a cherokee and will see if I can jury rig it by cutting off the elbow and attaching the cherokee end . It tore off the plastic pipe right where the rubber attached
