Let's just say that I have no confidence in any of the information received to date.

Reviewing it isn't going to gain any confidence.

I'm trying to get some confirmation regarding the simple valve body modification to move the spring in the governor boost pressure valve............

If I cannot get that............I'm going to purse one of the diesel valve bodies............which I'm quite sure will work fine...........although one of them also stated that the shift points won't be right.
