53 - 56 Ford F100 Frame Dimensions

Looking for 1953 - 1956 Ford F100 frame dimensions. Am starting installation of a TCI-Mustang II front crossmember. Instructions from TCI show location for crossmember measured from front shock mounting holes. I got ahead of myself and welded all extra holes holes up including the holes I need to locate crossmember. Hoping to find frame dimensions so I can locate spindle centerline from the end of frame at the front. Wescott offers great information on earlier Ford frames, looking for something like this for truck frames.
Thanks

Do you still have enough of your old frame x-member and suspension mounts to determine the spindle centerline?? You could also work off this as a reference for locating the new x-member.

Go to www.ford-trucks.com and look at 46-60 forum. Do a search for your question, or post question and you will find the answer.
