spindle question

[Chevy350]

What are the discs from? 88-92 1LE F-body? If so, your stock spindles won't work. The inner bearings are correct, but the outer is larger, as well as the ears and holes for the caliper is too far in (meant for 11" discs). You will need spindles from '78-90 Caprice/Impala WAGON/9C1, which bolt right in and already have 12" discs, only 5x5" bolt pattern. Your stock calipers bolt on, so does the 1LE discs. (My brother has this combo on his 77 Caprice 2dr)

If the discs are LS1 Camaro 12x1.25, you can use your spindles. Just do the swap like you would do the C5 13" conversion. (Cut off ears, turn down stock disk to hub, mount caliper cradle with adapterplate)
