I looked for a shoe box Nova for about 6 months solid with no luck including some trips to Pomona. I just about gave up and started looking for a Tacoma, SC300, Vega and a few others I was thinking about as a back up. Patience is a virtue I do not possess.
One day my dad calls me and says "Some guy just came by and asked if I wanted to buy a 63". I went to look at it that night and the guy that owned it was an old high school buddy and he made me a great deal on it. Moral of the story, sometimes things are just meant to be so try and be patient.

I haven't seen any G #'s from Wayne Due's C4 front clip but they have 8" wheels up front with a 6.5 back space. I am hearing rumors Lateral Dynamics might be looking into a front clip in the not to distant future.
