anyone using Bolt-on front Coil-Over-Shock conversion for early Mustang and Cougars?

[medbali76]

I am thinking on a Coil-Over-Shock conversion for my 69 Cougar.
Since my roller control arms and the adjustable strut rods are brand new (from Opentrackerracing) I dont want to buy a complete new front suspension.
I found a conversion at Total Control Products but I dont know how good is that system compare to the "full" Coil-Over conversion systems.

This is the coil-over shock I am thinking on.
Does anyone have experience with them?
