Hoodicoff1 Posted July 7, 2005 Share Posted July 7, 2005 I am in the same boat as you, converting from A TH350 to a turbo 400, I actually found a u-joint at the parts store that has the bigger end caps on one side and the smaller end caps on the other side,workedlike a hotdamn Quote Link to comment Share on other sites More sharing options...
Guest Posted July 27, 2005 Share Posted July 27, 2005 could you have a turbo 375? I think thats basically a turbo 400 with a turbo 350 tail housing, try a turbo 350 yoke, it might fit, Jim Quote Link to comment Share on other sites More sharing options...
