What modifications would I need to do to take my old spindles and replace them with SN95 spindles?

 

For one, you'd need to convert to a mcpherson strut style suspension.

What exactly are you trying to do? If you're thinking about a disc brake conversion, there are much easier ways to do it.

 

Yeah I want to do disk brakes and I want to do a 5 lug conversion.

 

Most aftermarket kits you can use with 6cyl spindles, read the websites first.

 

Check out www.discbrakeswap.com. I just ordered one of those kits for my 67fb. Price is good, the kit comes with everything you need (minus hard brake lines), and I've heard support is excellent. Degins (I believe the guy that runs the business) posts here every now and then. In fact, he posted a couple days ago concerning a discussion about disc brake conversions.

If you've got larger wheels in mind and want to spend some money on abigger brake kit, there are kits available that use 13" rotors. I believe Mustang Steve's website (www.mustangsteve.com) has that kit.
