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?
To clarify, you are using stock sliding calipers? Not an SSBC conversion kit?
The 11.75" slider caliper brackets are reproduced. DoctorDiff is currently out of stock, but I'm sure he has an idea of when they'll be available. Supply chain issues have been affecting pretty much everybody in this industry

If i find the larger brackets i will need to use larger dust shields as well correct?
DoctorDiff sells dust shields that will work with the 11.75" rotors. But dust shields in general are pretty useless, they do a better job of trapping brake dust and heat close to the rotor than anything else.
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?
The 11.75" rotors use the same wheel bearings as all of the 73+ 10.95" rotors. If you have 73+ A/B/E/F/M/J/R spindles you can use 11.75" rotors as long as you get the 11.75" caliper brackets.
ive read that both the 11” and 11.75” rotors used the same brake pads is this true?
Yes. They use the same calipers, so the pads are the same. The only difference is that the factory '73-75 A-body slider calipers used 2.6" diameter caliper pistons. In '76 the A-bodies started using the same 2.75" pistons that the B/E bodies were already using. From there forward all the calipers had 2.75" pistons. As long as you match the type of caliper (slider vs pin type) to the style you already have, all you have to do is install the larger rotors and caliper brackets.
im also looking at going this route

I mean, I suppose. If I was going to spend $750 (just for calipers, brackets and rotors) though I would probably go with a kit that had a larger diameter rotor. For about another $100 you can run the 13" cobra style kit.
You can get a pair of plain 11.75" rotors for a little over $100, plus another $90 for the 11.75" brackets. Using your current slider calipers and volare spindles you've got 11.75" brakes for about $200. And the 11.75" brakes and stock calipers work pretty well, I ran 11.75" rotors and a set of E-body pin style calipers with the 2.75" pistons on my Challenger for like 70k miles, they worked great and still stopped the 275/40/17's I ran on that car.
