yeah, that was on purpose until I get it tuned. I gutted my cats and changed my pump/line/injector combo so much I'm a little worried about raw fuel fire when I get off the gas, oh and the blue flame from NOS, so if that isn't an issue after all is said and done and I have it tuned, I will slide them in a bit.

simple, it is the big dog and I never want to mess with my rear diff again, in fact as you race certain parts like engines, transmissions and rear diffs survive even when you move from car to car and this diff will be the diff on my primary race car no matter if it is this Cobra or my 99SS or whatever comes next.
