Upgrading to 11.75” discs on the front?

Im running 11” ssbc rotors up front with the slider type calipers. I would like to upgrade to the 11.75” rotors but seems the larger caliper brackets are hard to find?

If i find the larger brackets i will need to use larger dust shields as well correct?

also i already have the spindles that accept the lbp 11” rotors as found on the 79 volare, will the larger rotors fit my spindles?

ive read that both the 11” and 11.75” rotors used the same brake pads is this true?

anything else i need to consider?

im also looking at going this route
