The Wilwood 4-piston Dynalites are 5.25" center to center @ the mounting holes,the Wilwood single piston w /parking brake is 5.98", & the GM calipers are 5.50",mounting holes are for the GM's.
I was going to make a 2nd bracket that would bolt to the sky bracket, make it to mount both Wilwood calipers,so I could mount the single piston unit @ add the 4-piston @ a later date & still have a e-brake.
