The ball joint from Monte Carlo is much bigger. I used a hole saw and drill press then welded in a nee pipe for press fitting the new ball joint in.

I am glad this worked out for you as I have done this for several of my cars and my customers. If you grind on the top parts around the ball joint it will clear the top a arm. I have also center drilled them for speedo cables.

You can also modify the spindle to accept the bottom corvair ball joint as some people dont want to change bottom a arms.

thanks Michael. I was lost for a while with this project as I couldn't work around the ball join depth difference and was trying to find the info that you gave me about the tappers being the same. then everything was easier. but the lower a-arm was a little challenging and I sure we still have a long way to go with figuring out the alignment on this car now.

the center drill is great Michael. makes for one less thing to purchase for those customers that want this kit on their car. I do think that the savings and style you gain with doing this mod is better on the pocket book.

stumbled on this; one may want to look at the "Mustang-II" parts, the spindles are about 1/2" taller at the Upper/Lower balljoints, with the upper BJ location on the spindle "in" further but Michael could probably re-machine and locate the BJ location easy..the lower control arms between the "Mustang" and Corvair appear to be 1/2" different between the spring and replaceable/cheap/beefier Mustang lower BJ, but nearly 'identical'..The (Mustang II )rotor is available new and used, stock or dropped, and is 9-1/4" with new available in the 5x4-3/4 GM lug pattern (I have a pair..), and these *may* fit inside 13" wheels..cast-in steering arms are shorter too, for the rack/pinion steering..

USAF_vair: I'm assuming you got to run this setup a little over the summer. How did it perform? Do the steering arms on the G-body spindles change the steering ratio? I bought the 4x4 S-10 discs to use the caliper adapter plates but also have a set of 2" drop S-10 spindles on the shelf. Any input would be appreciated.
You're unique, just like everyone else.

Did you say the total width increased by two inches?

That suggests the mounting face of the disk brake assembly is 1" farther from the ball joints.
I guess a line going through the two ball joints must have about the same angle as the Corvair spindle did, because you've been able to get it aligned?

So, you might see a bit more steering wheel kick when you hit a bump or pothole with only one wheel, due to greater offset.
But 1" isn't much in modern terms.

Why did you cut the top mounting pad of the spindle like that?
Does that part of the taper in the spindle fit the Corvair ball joint stud, or did you have to ream it?

cheers

Yes guys got to run the kit on my car all summer. Did. Not have any issues with the kit other than my stock springs are to weak
I have plan on making a adjustable insert for the factory springs which will prevent a coil from being able to compress which should help me with my issue of rubbing the front tires on the top of the wheel wells.
I have no issues with rubbing on the fenders.

I have not noticed any type of bump steer issues and have drove the car many times down rough county roads.

As for the milling of the top ball joint. The joint taper are the same. Just the ball joint tapers to a bigger size on the Monte or S 10. When you take the corvair ball joint and put it into an unmilled joint hole. There is no way to install the castle nut.

Specifically, what Monte Carlo or S10 did the spindles come from originally?

G body era spindles are what you want. More specifically the 1980-88 models which have a larger bearing would be my recommendation.
1966 Corsa turbo
1969 Monza convertible
1987 Buick Grand National

not sure about the drop spindle, but its not hard to make caliper brackets for disk brakes,, I was able to make C4 corvette rotors, calipers, and pads work, which stop very very well
Honda B20 turbo powered corvair. Is it the first honda powered corvair out there?
