SPC Mustang II Adjustable Upper Control Arm Install

[81dmc]

I am installing Mustang II upper control arms from SPC. These do require reaming of steering knuckle. Upper taper is simply made to be an exact same size as the OE lower ball joint taper using your choice of 7 degree ball joint reamer. This setup is easily rebuildable and allows fine tuning for caster and camber.


SPC arms come with ball joints that are way too large, so 2x 97001 ball joints are needed.

Also, SPC arms use 5/8 ID bushings. SPC sells spacer adapters for bushings which are p/n 944505. 4 of them are needed.

Finally inner part of arm will hit frame if steel spacers between arm and frame are not used. I plan to use McMaster Carr 1/2"ID x 1"OD x 1"W spacers for forward part of arm and 1/2"ID x 1"OD x 1/2"W spacers for rear mount of arm to frame. Using 1/2"-20 x 12" bolts from McMaster to secure.

SPC Arms- 97260

Ball joints- 97001

Bushing spacers- 944505




These fit the stock 14” wheels. Will post pics once fully installed.

To those reading this. This is not a Timeless Steel Garage through SPC Control arm kit. There are no mustang 2 components in my kit. My kit was designed and tested over the course of almost 2 years and is backed by SPC. This posted by this gentleman above ^^^^is not. SPC sells the real kit exclusively through me.

Did I mention you?

What is problem here?





Edit: And I first messaged you and figured you were done as I got no response. So I decided to DIY my own setup. Uses same 97001 ball joint that you use in your setup.


At the end of the day, I’m allowed to post what I want on custom setups that I run. I am not selling anything. Rather, I’m making it easy for folks to run whatever they choose.

Got some parts today to do a good test fit, and it clears frame. I'm currently waiting on steering knuckles to get it all together.

Is that spacer plate on the body original to your car? Never seen that one. I see you have an "early" VIN.

That plate above upper shock bolt?

800 series vin so yeah very early.

Hmmm you learn something new every day. The later plates don't go up the body, they are flat with a flange in the edge that follows the body contour upwards for only a centimeter.

Here is the newer style. I had a bolt and nut in it to hold it in place while the panel bond cured. The front body bolt runs through It and goes into the shock tower.

Still test fitting etc. But so far, RH side is together. Clearance between forward part of control arm and rim is very close, but that could be increased by using a slightly shorter 3/4" spacer in front rather than the 1" long I have installed.

Are the ball joints that come with the SPC arms regular mustang ii ball joints?
