I've got the connecting front brace 6756 for sale. $40 + shipping. I don't have the nuts and bolts for it though since I'm still using the front frame braces which use the same bolts. Maybe you can get them with the front frame braces 6564 from someone. (By the way, I found the front frame braces on a Grand Prix in the junkyard.) If not, you can get them at your local hardware store. If I'm not mistaken, the bolts are M12x1.75 - 30mm long. You'll need two nuts, two bolts and two washers.
I'm selling the connecting front brace because it DOES NOT fit with my front mount intercooler. The FMIC pipes running under the radiator support don't clear the brace. If you're running a stock location intercooler, it fits (but I think I had to notch my plastic air dam thing-a-ma-bob for clearance.)
If you're interested, send me you zip code and I'll send you a shipping cost.
