LG A-arm help

I have LG adjustable lower A-arms on my T/A, and now I have a slight problem. When I installed the arms, I took it to a shop just up the road, and they said they could do the alignment. Well, they did an alignment, but it's nowhere near the numbers I asked for, and I'm too tired of dealing with them to go back anymore. I found another shop (recommended by a friend) that does great work, and they are willing to align the arms, despite the PITA involved. However, they want me to return the arms to stock length before I bring it in, so they can start from scratch.

My propblem: I sold my original arms, and do not have the measurements for them. Can anyone provide the stock length measurements for the stock control arms (balljoint to bushing bolt hole, or point-to-point of some sort). Thanks for the help!

Steve,
I am going to take it to Gran Turismo East; that is, unless you know of another shop that you recommend. It's really difficult to find people willing to mess with these A-Arms, they are awesome pieces, but a real pain to adjust (no on-car adjusting).

No, that's the place I was going to recommend. They are without a ddubt, the best in the city. Tell them the guy with the blue Camaro the autocross's sent you there (not that they'll charge you any less!!!! ).

I have them do all my alignment work and I also have all my tires dropped shipped there from TireRack for mounting and balancing. Great guys that REALLY know there stuff.

I don't get it. I thought the purpose of these heim A Arms was to facilitate the adjustability of them and allow the negative camber that is otherwise prevented by stock A Arms???

I just finished this upgrade. It can definitely be frustrating. I was lucky in that I had a car that has G2 lowers I could pattern after to get close.

But, oh man ... once they are on ... holy sheet ....

Measuring from the BOTTOM side of the stock A-Arm, from the centerline of the lower ball joint (flat side) to the center of the bolt holes, measured on the BACKSIDE of the A-Arm bushings:

14 7/8" on the camber mount
18 1/8" on the caster mount
