62/71/13ss turbine change to your 68????

What will need to be done to change my HTT 62/71/13ss to your 68 turbine? Is it just a wheel change or will some machining need to be done to the exhaust housing or will I need a new housing? PM me a price and post details on here if you don't mind, please. This tractor turbine just isn't working out towing heavy.


Thanks,

I have an 04.5 running a Smarty, Quad pressure box, 15 blade left cut converter from Goerend, 4.10 gears and the usual other stuff. I will be upgrading the injectors later.
