The lift kit comes from TM. But in a pinch you can make one yourself. It is two pieces of box tubing, ( 2 inch ? ) drilled to match the current holes in the TM frame / axle and 4 longer bolts with nuts and washers. Try TM first. Mark everything as you go. I did one side at a time after marking eveything. Had to grind / cut some tack welds but other than that it just takes time. Sorry to hear about the plumbing.... been there.... done that....
Not just TM with that problem. Good luck!
