Here is a EASY one, I HOPE?

I have the factory A/C brace for a 318 cast iron 2bbl. intake. It measures about 8" like you stated but I can't promise the angles will be correct for your aftermarket intake. You should be able to modify it a bit if you have to. $10 plus $.88 tax plus $5.20 shipping to you via USPS priority mail.
Thanks, Mark
