HELP! 11.75" Disc Conversion - Bearings, Seals Etc

I do believe all the inner and outer bearings and seals are the same 73-87 on A, B, E, R, F, M and J body cars regardless of 10.87 or 11.75 disks. All the spindles accept the same bearings regardless of the groupings as well (A & E body spindles vs 73+B, R, F, M & J body spindles)
