Disc brake advice please

Think I will just swap over to the 75 dart setup to use the LBP Rallye's and sell my KH setup that came on the car along with the SBP Rallye's. 1/2" studs seem to be the better option over the 7/16".

It's a great day that you have both options. Some other nutjob like me will want the KH setup lol....
