SRT8CUDA Build

Thinking of picking up the same front end from RMS. Just wondering how do you like it,and how's the quality?
The quality is excellent, but the most important thing is customer service. Bill Reilly is absolutely great to deal with. I've had several questions during the installation and he is always willing and able to help.
For example- I could not figure out how to fit the steering rack into position (it is a very tight fit) and he used one of the cars in the shop and took a video and posted it on YouTube for me!!!!
