From those who ran either one, would you do it again and are you satisfied with the results? I am debating on which one to put into my 69 RR so I'd like to hear about both. My RR has a 512 and a 3:54 Dana if that matters. The thing I didn't like about the Keisler kit is that it isn't centered in the fact 4spd hump (i.e. my carpet kit has to be changed now). Basically do you gain much of an advantage by using the Keisler kit vs the Passon trans for occaisional daily & highway driving?
