You would first have to decide how low/high you want your truck to ride and then factor in the wheel/tire combo as tire height has some effect on it.

I don't think that most crossmember manufactures vary much on the distance from the lower A arm bolts to the bottom of the frame rail but that distance is going to be the ride height factor from one kit to another. The theory being that the lower control arms will be level across at static ride height if installed correctly. That is what you want to ask about when contacting the various vendors about their product though.

Word to the wise, don't bite off and buy a "universal" kit because it costs less unless you are hell for good at fitting and have plenty of patience. I have one and it is a bit of a challenge to figure out where to cut it to get it to fit right. As soon as I have the Cad 500 in my 71 and have it running and driving so I can haul the frame to the sandblaster and haul parts around I am going to seriously attack it.
