MO WTB: 71-72 (see pic) frame mounted air deflectors & more

[Ozark Tim]

Looking for the air deflectors that mount to the frame and the rear bolt of the engine mount stand. Both L & R. This is the part that helps blow air over the rear 2 plugs on the V8's. Mine is a small block. See picture.
Also need 4 OEM bumper bolts with the stainless caps (acorn style or whatever they are called). I dont think there is a repop on these???
Just to throw it out there a gain I am looking for a driver quality chrome rear sport bumer. Dont mind a few minor pits or scratches but not bent or dented unless it is really minor.
Thanks, Tim
