bottom measurement of bosch 2x2 coil packs

I am looking for someone who has access to a bosch 2x2 coil pack from a landrover (the same one alot of people use for wasted spark) and can give me the bottom measure for the "buttcheeks" to sit down so I can bolt the pack to a metal plate I am making..but I do not have the coil pack with me.

Or if somebody had the original mointing plate that came on the landrovers, I need the opening measurement.

Like so...

Cut a hole that is less than the 4 mounting points (90x52). For whatever reason they only posted the dimensions of one side of the "cheeks".

Awesome, thanks so much.
