9 inch drums to 10 inch drums to front disks

ok, thank you, and at the risk of sounding dumb, what else am I going to need with those? such as brackets and such, or more importantly, what kind of donor cars would I need to look at to get what I need. I have performed countless google searches and I've received so much contradicting information that it has all just left me confused.

You will need the 73 and later upper control arm, spindles and discs...

Those take the larger upper ball joint...
