get the pedestool mount style, I'm not up to par with my "brands" but I "think" those were the kind used on the cobras, someone else may clarify. you can get these anywhere (ebay, corral) for around $100 -$125 shipped for the 1.7's used. don't forget to pick up a shim kit if they don't throw them in.
Hey just wanted to say thanks for all the input and info. Last ? is what cam would all of you recomend. Mainly a street car with the occasional visit to the locar airport drags.
