G.M. Ignition coil

I've been using this on my '80 without issues for many years so it was a no-brainer for my '79 Project.  I cleaned up the wiring this time.  Remove the 6 leads, diconnect the Bullets and small plug, undo 2 bolts and it's out !  
 
 
 

I went looking for that coil a couple of years ago and couldn't find it. What make and model did it fit and physical dimensions is it please ?
Hoping it's as small as the IGN-6 I got from  DIY Aututune. I had one and when trying to make a new bracket to fit it under the fuel tank, fumbled the coil, it hit the floor and smashed off 3 of the coil towers. $79 US down the drain.

Just put it in and am tuning so no dimensions for now.  You merely need to drill 2 new holes in the mounting plate.  

 
 

This position gives ample clearance between the front of the Coil and the Thermostat housing.
