65 dartcharger 3.55 8 3/4 suregrip going in

Just got my 8 3/4 3.55 suregrip rear end sbp this morning .. needs a little clean up and slide her in the 65 dartcharger 273 4 sp.
decided this is the way to go on the rear end. No peanut 7.25 rear end for this dartcharger 4sp.
this should wake this car up big time !......... has a peanut 7.25 2.93 rear end in it now ..
can't wait to see the difference in performance.
