alignment question

[Hank70SS]

Do the after market arms use a different shaft than the stock one?

[mestorod70]

The arms are made by CCP and have no built in + caster.
I did the longer bolt mod but only got to +1.5 deg
Im wondering if I can relocate the upper ball joint.

I finaly broke down and got some different upper arms.
I now have +5 deg caster...and -1/2 camber with 1/8 toe in.
The problem is my steering wheel wont return to center without help
when turning left.
In a right turn it does just fine.
All joints are fairly new and move freely.
Im wondering if its in the box?....I did loosen up the adjustment in the box
to give it some slop...but no diference.
Anyone have an idea whats going on here.
Thanks.....mick.
