Cost me $200 for the gate mod. I removed the turbine housing and gave it too him though. It would obviously cost more if he had top remove the housing for you. I didn't take a photo of the welded internal gate. He was very thorough thou, he welded it completely and even welded up the swing arm hole. If you are interested, check out his Facebook page, it shows a lot of his handy work, he does top grade fabrication work.
