RideTech 67-70 Mustang rear 4 link suspension question

[medbali76]

I have a ridetech 67-70 Mustang 4 link suspension for my 69 Cougar that we would like to install into a 70 Mustang.
I got this kit with longer control arms to be able to use it in the Cougar (the Cougars have longer wheelbase). I am not sure about the upper arm but the lower arm is longer for sure. I would need the exact lenght of these control arms originally built for the Mustangs because I have to cut them to fit for the 70 Mustang. Can somebody help me out?

Thanks.

Medbali76,

If you look in our instructions for the Mustang it shows the center-to-center dimension at 21.75" for the lower bars:
