How hard/whats needed to change.....

The car does have a 7 1/4. But it does have front discs and no factory A/C so it would be a pretty good canidate. I just have to decide if I want to spend $1700-$2000 on another project car instead of starting on my FJ5 70 Duster. I already have all the parts I need for the 70 model, but a factory manual floor shift car has me thinking........again.........
