This is regarding a 32 ford highboy chassis. I am having trouble trying to decide whether or not i need to NOTCH the frame rails in front just above the front transverse spring? The guy building my frame says no...dont need it...but i've been seeing it a lot on other cars...i spoke at lenth today with a guy in Concord Cal. that has two 32 rrods. both highboys, he says i will bottom out if i dont do it? Ive seen cars built by big name guys without notches. I'm really mixed up, and want to get this RIGHT. Using super bell 4 inch drop Ibeam with posie type spring NOT a monoleaf. ...WHAT TO DO? please share experiences . Thanks
