I have never done this swap.
I have a set of Granada spindles and disks though. Sorry not for sale. I took them off a Mustang.LOL
There are lots of sites that have the info you need.

These are for the Stang swap, but it is basicly the same.
If it is a budget thing then you can save some $, but you can get all the parts need to bring it too stock disc from Dearborn.
