[QUOTE=slenning;330337]I have a Speed Kit 3 in my 69. Wasn't too bad to install, just take your time cutting. It rides and handles real well. But I am seriously thinking of replacing mine with a full DSE subframe real soon. I track mine and would really like to get bigger rubber on the front. A 245 tire is about all you can do on the stock subframe.
