1971 Duster 340 Front Drum to Disc Brake Conversion

My car (original 10" front drum brakes) currently has a Wilwood 140-2713 front drag brake conversion, 4.5" BBP. The Wilwood rotor hub diameter is 81.5 mm (3.21 inch) which won't allow me to run OEM steel rallye wheels (2.75" center bore) as I would like to do.

Also, the Wilwood drilled/slotted drag brake rotors are noisy. I want to change out the Wilwood kit out for a different brand front disc brake conversion kit (not a '73+ rotor/spindle/upper control arm swap) with (a) solid rotors, (b) BBP and (c) 2.75" hub diameter to match the OEM rallye wheel's smaller center bore. Does anyone know if such a front conversion kit with (a), (b) and (c) even exists? Please don't ask me to search the forums - I already did and couldn't come up with the info I'm looking for. Thanks FABO nation from a newbie.
