TTI hookers are junk. I have TTI full exhaust on my challenger awesome fit perfect never leaked. Hooker super comps on my 69 superbee junk hit both frame rails rubbed on the torsion bars. Had to change gaskets every two months.
The B and E body's have different track widths so there's no conversion kit. you can cut Down the axles and weld on new ends to get the proper length, or if your too short u have to completely remove the tubes and get new ones welded in then weld the ends on.
