You need better directions on installation of the shocks and angle of the kingpin. More pictures would help.

My son has 1964 Falcon. It has the 4 lug front drum brakes. We do not know what rims we will be putting on the car. (15x6's or 7's most likely, Cragar S/S's) Can I still use the 4 lug drums to make my measurements ?? Do I need to "add" any inches to compensate for the 15" rim ?? Is there any welding required ?? And lastly, will his stock master cylinder work with the new disc brakes ??

I'm curious as to whether this will fit my 1953 IH Travelall R110. It's 54 inches from drum to drum across the front and about one foot from drum to leafs. Please let me know as my wheel hub bearing has begun to wobble on the driver side and I need to replace either those or the entire front. Thanks!!
