Will Granada spindles interchange with Mustang II spindles? The bearings are the same but will the tie rods and ball joints work?
Can I take the Granada brake mount and use it on the Mustang II spindles along with the rotors and brakes?

Can't help you. I do know the Granada spindles interchange with Mustang spindles, you just need to use Granada tierods, I believe.

LOL, this project of mine is getting out of hand!
I have a set of Granada spindles and am ready to do the swap. I want to use large wheels with alot of backspacing 5 3/4" as you might know the upper balljoint limits the backspacing to approx 4 3/4" so to solve that problem I need to get the upper balljoint closer to the spindles.
I can do this by using a dropped spindle. I have found one supplier for Granada dropped spindles for 400.00 (fatman fabrication)they provide a 2" drop perfect! but the 400.00 price tag isn't so perfect! Which then brings me to Mustang II spindles. You can buy them for 260.00 so a little cheaper. If the Mustang II spindles will work with the ball joints, tierods and calipers, then I can go this route and the caliper will be on the same side as original.
So why all this trouble? I can fit 9" wide tires under the fenders with no problems and use those new Mustang retro rims. I can get a set of four rims for 125.00 each which is alot better then 250.00 each. I will more then likely come out about the same in price either way, but if I use more backspace I get a car that handles well and has wide tires that are under the fenders at no expense of steering wheel effort...plus it would be cool to ge those rims to fit...without spacers wich will hurt performance.

Mustang II spindles won't work...the tierod arm is too short..so that leaves me with the 2" drop Granada spindles...wish I could find some cheaper. Anyone ever seen ao used these before...probably not?

When I was thinking about useing the MII spindles I thought I could use them but backwards...The tierod ends aren't long enough or low enough...this would cause severe bumpsteer...so no good. The idea is to give an alternative for wheels that are being made while making it cheaper too. I figure if the wheels I want are 250.00ea. (rear) and 390.00ea. (front) that's 1280.00 for JUST RIMS! I feel I can do it cheaper and improve the steering and handling another way.
I'm soooo close it hurts, It's driving me nuts! LOL! The rear wheels fit perfect no modification at all for my car (granada 9")
And the fronts I have all figured out I just need the parts to do it...arrrrgggg.Thanks for the help.

Try looking for a place that will cut your spindles for you - if that will solve your problem. You might have hooked up someone who thinks they have a niche market going and is trying to rake your poor budget a few times over the burning embers. My friend just had his spindles cut on his track only Datsun 510 for 80 bucks a side. I can give you info on where he went, but its in California if you don't mind the shipping costs.

Yes please, If you can get me any info I would appreciate it. Now did they make completly new spindles or alter his stock ones? Just don't understand what you meant by "cut" my spindles? Thank you for your help.
Like I said, my options are begining to narrow to the fatman fabrication spindles. I need to call to confirm a few things the web site I saw the 455.00 price on seems old and may not apply anymore? I am open to any ideas you guys might have.

Well I was mistaken, a 510 doesn't even have an upper control arm. It uses MacPherson struts, which was what he was cutting to lower his car an inch. Sorry for the mis-information.

Reversing the MII spindles causes them to have severe ackermann angle problems. The steering arms are angled outward from the pivot centerline for a front steer application, not inward like the rear steer Mustang/Granada. Using them backwards turns the wheels at the wrong rate causing severe tire scrub.

A while back, I took a number of pics while comparing MII spindles to V8 spindles. Take a look, maybe it will help you some.(BTW, I paid $30 for the pair of them) http://pages.prodigy.net/al.martin/MII/MII-1.jpg

66 coupe, I haven't actualy seen a mustangII spindle with my own eyes, so I wasn't aware of the akerman angle problem, I should have figured. I've desided it wouldn't work anyway due to the tierod arm not being long enough or low enough. Can you say bumpsteer! Al, you are the man! If I could find pictures like that of everything I need, this stuff would be simple! You wouldn't happen to have any Fatman fabrication dropped Granada spindle pictures? Nah, didn't think so. Were you considering the MII spindles? Rack and pinion? Thanks for your help! I realy appreciate those pictures and everyones input a lot!

I took those pictures very early in my quest to find a way to install a MII rack and spindles on a stock suspension setup. I figured out how to do it (I think), but it would be easier to just weld in the MII crossmember.My recent antics have me placing the MII rack in the rear steer position. The MII rack has the best dimensions I have found of any rack to fit there and work. Plus, they are cheap and easy to find anywhere and in performance form, various ratios, power or manual etc... That leads to the problem with a front-steer rack mounted in a rear-steer position. This is the reversing gear box I am working on to replace the existing steering box to solve that problem.  The plan is to mount a block (much like Pro-Motorsports bump steer kit) on the steering arm that will move the outer tie rod in closer to the king pin to make sure no steering radius is lost. I have many plans - just no time to work on them. Al ------------------
