How close is the fit?  Is there an option to remove a little material from the caliper to get it to fit or if its close can you put a spacer on the front of the hub?  Sometimes adding a spacer will get the clearance you need because the rim opens up as it moves away from the mounting flange.  I would not do the Granada spindles.  They will lower the front end about 1", they will throw off the camber curve and the ackerman angle will be off.  The LTD II spindles will work BUT the lower your car sits the less camber you will get.  At OEM ride height they work fine and there should bairly be enough camber adjustment to get it to 0 but any height below stock and your camber numbers will go positive.  That is why I am dumping my LTD II spindles because my front end sits about 1" lower than stock. The 69 LTD spindles are probably your best option on a budget.  They should fit in the rims and the geometry is identical to the early Galaxie. Keep in mind that replacement rotors and calipers are expensive.  If you want to spend some money Wilwood offers a kit to work with the OEM spindles. The list price is $744.79, with my comercial account with them I could get you a set for less than that but I am not sure how much less.
