That kit does look OK but in a conversion like this or anything for the matter, cheaper isn't always the best route to go. I'd hate to see anyone pay for this then finding they have to turn around and buy a Donato kit. Looks OK though and is a good price but you have to wonder. A good converter will set you back $700-$900+ so looking at the rest of the kit if the converter is any good it's realistically a $900-$1,000 kit? vs. Johns $2,295. People don't sell at a loss so I'm guessing the quality of his stuff isn't as good. Having said that, it'll probably be OK but I'll let someone else try it first and see how they like it. :laugh:
Keep in mind that's for a TH400 so it may or may not fit a 4L80E.
