Pros an Cons: SBP v LBP

what is the best and cheapest set of front discs? are they LBP? as far as correct restoration, i dont really care. im putting a 360 into the dang thing and jus makin it look like a Swinger 340. i want to restore the car as much to era correct but i want the mechanics of the thing to be more modern. better handling, more economical, but with a vintage feel. so i guess its a renound "Change to LBP" from the majority of my FABO brethren(and sistren?).

now then, since i currently have original 9" drums on all corners, i also have an 8 3/4 w/ 10" drums (which i want for the rear). given that, what is the EXACT parts list i need to change to LBP discs? do i need to go find 10" spindles and just get a kit or is there a better way? im looking for the quickest and cheapest swap possible.

Also, when i get to this point in my project, is there anyone local with knowledge about this swap willing to help? Thanks!
