Customs '58 Chevy - How To Extend Upper A Arms??

I seem to recall an old Hamb tech thread on how to extend stock Chevy (58-64) A arms.
I've got a '58 Nomad that we lowered by cutting the springs and have about a 4 degree negative camber situation I'm trying to correct.
To extend the stock upper A arms, I'm curious as to where to cut them at, things to watch for, ways to reinforce them..etc.
In talking with the alignment shop, I need to extend them about 3/4". Global can make me a pair ($$$$) but I can't swing that right now so looking for options with the stock ones.

 

how do they mount to the frame ? top or side

 

They mount to the top of the frame with the crossbar shaft. I can get offset shafts but only 1 degree.

 

Could you shorten the lower arms instead??

 

I shortened lower arm, AND steering rods.
much easier..

 

We used to heat & bend the upper part of the spindles with a Porta-power. There was this one guy at the alignment shop that knew just the right amount to squeeze ...

 

No need to cut, use spacers.

 

Possibly... That would also help with keeping the top of the tire away from the fender during turns.

Where did you cut them... maybe towards the inside part of the arm??

Not sure what you mean by using spacers. All alignment shims are out of the top arm and the bottom arm is in a fixed location.

 

I'd be up for that. Both the alignment shop and frame shop here ( both are well known for great work) said "can't help ya". So...I need to figure out how to get some adjustment back into the thing.

 

I have some 1" upperball joint spacers if that would help?

 

Thanks man...I appreciate that. So does an upper ball joint spacer get that upper A arm back up enough to get some positive camber back in it?

 

Can't you just use longer bolts and more spacers, or move the shaft to the outside of the frame mounting flange.
