6 lug rotors

[dinnut]

im looking to convert my 70 to disc brakes. i have the complete assembly from spindle to dust cover that i bought from slicknsmooth72. now. im either going to leave the 5 lug and go over to 5 lug or just stick a 6 lug rotor in there. all the catalog parts places sells the 6 lug rotors and im wondering what vehicle they are from. id like to not pay like 80 a rotor and possibly get them cheaper from an auto parts store. anybody know what vehicle these are from? 6 lug discs in the same boltpattern as our trucks?

this is a side thought:
if i change over to 5 lug im going to stick some chrome camaro ralleys on there and lower it a little and make it more of a classic than my original thought of bags and 20s. i may still goto bags later... but i dont know... for now i just want discs

not the best photoshop in the world but just what i might do... with 5 lugs
