Quick 5 lug conversion question... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Wondering if anyone can help with a control arm question...

What is the difference in the upper control arms from 67-70 and 71-72.. would it just be the size of the ball joints?

I am wanting to use both upper and lowers from a 72 on my 69 cross member during the disc brake conversion.

Thanks in advance.

Thank you very much. That helps a lot and what I take away from it is:

You match ball joints to the year of the spindles and it doesn't matter what year of 67-72 control arms you use.

Here is another thread on the disc brake swap that you might be interested in.

Balljoint is the only difference in the 67-72 arms.
C20/C30 lower arms however are different.
Larger balljoint hole.
