what parts are needed to put front disc on a 66 sport fury.

you need the spindles and calipers from any 69-73 c-body with disc brakes.
The 69-72 being a bit more expensive for replacement discs. 73 being the most desirable, but getting harder to find.

I have a set of the 73.If you want to p.m me.

Theres a really nice writeup about the C body Disc brake swap here:

I did the 73 swap on my 65 newport.......very easy and works great !
