Need help with a RideTech Question

[Motown 454]

I have an older Ride Tech Airbar, rear set up on my 69 Camaro. When it was installed the lower links were shortened or lengthened, I don't know how much. Now it's a two man job to try to get the shock on they don't sit on the shock mount straight.
Does any one know the length of the lower arm when you use these welded on brackets?



Here's the way the shocks fit.






I took a quick measurent and got 22-1/2"



Any help would be appreciated.
