There is a way to do it by keeping your drum spindles now.
I think it is "Scarebird" or something like that.
But I've always done it the bolt on way.
If you do, go with the larger "Cordoba" rotors.
Since you will need to buy rotors anyway.
It will help.
And with the larger rotors you will need the larger caliper adapters.
Doctor Diff is a good source but I don't see them on there now.

But with the larger rotors 14 inch rims won't clear.
You will need 15 inch rims.
Brake lines from a St. Regis will work.
You can junk yard the spindles.
Used to be that was all.
Now they are reproduced.

If they ever get off the ships from Taiwan or where ever.

Myself?
I wouldn't get wrapped around the axle on that.
If I had a pair of spare F body spindles laying around I would try them and see if there was a problem
WAIT!
I do have a spare pair laying around.
And if your car has a factor anti sway bar you will need to swap the spindles side to side to move the calipers to the rear.
