I got the stuff and it is nice for the price.
However, with the provided mounting blocks there is no way a TH350 cable can be attached. Since I'm using the braided throttle cable and mounting block for it, the leftover block is the one for the stock throttle cable. It has a much smaller square hole than the TH350 needs and trying to mill/file the hole larger would not leave enough "meat" to make me comfortable using it.
An email to the tecnical support guy at Skip W asking if they sold the size mounting block I need got me no response.
For my needs, attaching a TH350 cable to the bracket, this brackets included harware and companies lack of response is a complete fail. I wish I lived near a place like Summit where you could go there and see an item before purchasing it. I do like the braided throttle cable though.
