Mustang guys with the Maximum Motorsports rear spherical upper mount...

If any of you have 5 minutes, can you go out and measure the length, width and height of the MM upper mount on top of your rear shock towers? I'm looking for an option for the pin top shocks on C5 Vettes and there isn't much room in the upper shock perches and the MM mount came to mind as an option. There is a company making a delrin option to replace the rubber mounts but I think over time, that will fail in a coil over setup especially if exposed to super cold temps.

Muchos Gracias!
