guys i am new to this. just bought a 31' ford sedan and was wondering what was to best way to get the rear lowered the most without cutting into the frame.
There are a few options....T spring, revise eye, remove some springs. Do a search and you will find a shit load of information. I would also recommend you go buy Les Andrews Model A Mechanics Handbook Vol. I and II. along with Mike Bishop/Vern Tardel's book on tradition hot rods. Have fun and post some pictures!
