As I posted in the CF thread, you guys should check out VTSRacing.com. I have had a lot of dealings with them regarding custom 1 off work on my Cobra & Lightning. Quality is great and the CS is even better!
Oh and all of the custom parts that I had made ended up being very reasonably priced. All I really did was have them expand the capacity of the OEM tanks so they would bolt in the same place.
Hope this helps!
