Charlie's Muffler shop in Yucca Valley CA has an outdoor lift and can do any welding you need. I've used him a few times with my 1985 total dolphin for mufflers pipes spring helpers bumpers among other things. The lift is perfect size for my 21 foot dolphin. He also accepts credit cards and has fair prices. I've broken down the prices I've paid there and he's very reasonable. good luck
