Tube Control arms on 86 C20

[demian5]

My son scored a set of lifted tubular control arms. However, they are for a c10.

We would like to convert them over to use the brakes and keep 8 lug, but:

• Lower ball joints wont work. Do they make another ball joint that fits in the c10 hole of the arm that bolts to the c20 spindle? Other option is uni ball.
• Upper shaft wont work. Do they make a upper shaft that uses bushings instead of the screw on caps so it will fit the arm and the bolts in the frame?

Anyone have any experience with this?

The C20 was not loved by the after market.

As far as the hole in the a-arms. I believe you mean the modern type that sets into a socket. My limited knowledge as I found a set a fabtach probably mid travel a-arms in pick a part once, and when I called around. I was told i would have to replace the cup in order to get the ball joint size I needed.

I sold them for quite a bit of money, and never looked back.

But like i was told you can get the proper ball joint since, and cup as a kit. Then you could have it welded in, and your set. I would use a porta band to extricate the original cup, or a grinder.

As for the upper shaft the set I had looked like it would bolt on, and I went no further after finding out about the ball joints.
