Tire dimension charts are on many manufacturerвЂ™s websites. Spindle height is relative to tire size and will be close to the tireвЂ™s radius minus 1/2вЂќ. Dropped spindles can be use to lower the frame 2вЂќ from that.

In general, the ideal height of the bottom of the frame at the crossmember would be the same height as the spindle, plus or minus 1вЂќ for stock spindles. вЂ“ The height of the frame relative to the height of the spindle. For frames wider or narrower than ideal, there are workarounds. Add 2вЂќ to that for the other kits as they increase in width. Generally speaking, the 56-1/2вЂќ kit вЂњlikesвЂќ a frame width of 26 вЂ“ 30вЂќ outside. We refer to track width as the dimension from tire tread center to center. The Mustang II crossmember to use depends on several things: IвЂ™ve come across this request and hope I can still help. These are the correct track width kits for the corresponding vehicles. Willys Pickup & Panel (with top hat frame), 1946-54 Before making the crossmember shorter, confirm that a rack will be available. Some machine shops will do this and there are aftermarket companies that make custom-length Mustang II racks. It will be necessary to use a shorter than stock rack. Subtract the lower arm pivot dimension from 22-1/4вЂќ and you have the amount that the crossmember should have removed from between the rack mounts. Or mock up both sides and measure lower control arm pivots center-to-center. Measure from the frame centerline to the lower arm pivot and double that dimension. The tire should be very close to vertical. Put the assembly in position in the fender of the mock-up.

Mock up the wheel/tire, spindle, brake kit, rotor, and lower control arm. Get the upper and lower arms that you decide on. Shorter arms will mean a slightly choppier ride. Shorter control arms will move the pivot point out by their вЂњshortenedвЂќ amount, given that the spindle location does not change. See if there will be clearance issues because of this. When the crossmember gets shortened, the control arms will move closer together by the same amount.

The upper arm cross shafts on stock length arms will be about 29-1/2вЂќ center-to-center with a stock rotor-to-rotor face width of 56-1/2вЂќ.

Mock up the car at ride height and position the wheels and tires, front-to-back and at the desired track width.Д¬ompare the spindle height (the center of the wheel) to the height of the frame at the bottom. (Might as well get the calipers, too, but this wonвЂ™t affect the crossmember width.) Get the brake kit and rotors that will be used. Get the wheels and tires that will be used. Coil-overs will provide more spring to frame clearance and make it easier to dial in ride height and ride quality. Use our 56-1/2вЂќ kit, for either stock springs or coil-overs. Read all the way through this for best results. ItвЂ™s good to have the brake kit, rotors, wheels and tires before deciding how much the crossmember should be narrowed. Aftermarket brake kits and rotors can change this 56-1/2вЂќ dimension.

56-1/2вЂќ is the distance from the rotors wheel mounting face to face. We are often asked about making a Mustang II crossmember kit for a track width less than the stock 56-1/2вЂќ.

WeвЂ™d give you a price for the plates and you can decide if you want to order them or make your own. These worksheets can also give us the info we need to provide you with boxing plates. If you fill them out, take pictures of them, and email the pages back to us, we will give you drawings showing the sections to be removed.
