Hello, I am new here, need help

This forum seemed to be the right place for me to get some information. Maybe a member here has done what I am doing. I am installing new frame rails on a '53 Stude. I have all the dimensions I need except one. I had the engine /transmission and sheet metal off before I decided to make the swap.
Now I am looking foe a ride height from someone that has done a '53-'54 Stude. All I need is a measurement from the bottom of the frame to the ground. Does anyone have any idea or know someone with access to this measurement. I forgot to mention I also need to know wheel size. Thanks
