A-arm/Frame Dimension Question
I want to check the a-arm/shock tower frame cross dimension (a-arm to a-arm on a big block car) on my 72. I've searched the AIM, service manual, and the web for a length/number but no luck so far. Can anyone help out here? Also, where exactly do you measure too to check this?

The measurement between the shock towers is 26-3/8"
You check where the shims touch the frame right where the studs come through the frame that hold the upper control arm shafts

One of the diagrams you'll find is from a 79 frame manual (same as the others)
There are a few threads here on the forum where it pops up (at least one I thanked someone for posting since I knew I'd need it, can't find that anywhere to give credit to

And the one that I referenced back to is from Van-Steel
