A follow up from my other post on 1966 spindles. TCP sells brand new spindles that are based on a 1970 Mustang for $350/pair and they say that they fit all years, but you may have to change the tie rod ends. Here's the link:

This got me thinking about my application. I need spindles for my 1966, but I also need suspension, brakes and steering. I plan on converting to rack and pinion and upgrading the front to disc brakes. If you look at the technical specification sheet in the upper right corner of the link, you will see that all year Mustang balljoints are compatible with their spindle which is based on the 1970 design, but I would need 1970 tie rod ends. So here's what I'm thinking. I purchase 1966 suspension to keep the geometry correct, a front disc brake package for a 1970 that comes with spindles, and a 1966 R&P set up with 1970 tie rod ends. I can get all of this for about $2,500 which is a very fair price. Sorry for the long note, but please share your thoughts!

 

I nwould repalce the entire suspension with one of the newer systems using coilovers and disc brakes. Something like Fat Man Fabrications, or one of the MII assemblies. If you're going to spend that much money and effort, I wouldn't be cobbling parts together.

I used a Flaming River manual R&P set up for my '66 coupe. Hated it. Column was cheesy and rough. Manual rack was difficult to turn . Nothing like the FFR. Would only suggest a power rack in a classic Mustang.

Scott, thanks for the info. I hadn't considered the bumpsteer issues, but do you think a bumpsteer kit that allows the adjustment of the tie rod end in relation to the spindle would work.
