Hello Flight Test, my name is Jesus, I live in Bruleson, right off Remfro Rd. I just removed the cab (COE GMC) of the original frame, you may want to look at my frame to see if there is some thing you can use, I am setting the cab on a mid 2000's ambulance rolling frame. It sounds like you are near Burleson, so give me a call if you want to meet with me. 817-657-1832
