Another rookie question

Where can I find a chart that gives actual engine dimensions?
For example, I'm wondering, will Aerotech's single use E moters(say the E-30) fit in the E-9 motor mount on my 4" Estes V-2?
Is the Estes C-11 the same dimension as a C-6? I see Aerotech makes a D motor that is 18mm. What's the length, will it fit my stock Big Bertha mount?
Does Areotech make reloadable motors that will fit the 4" Estes V-2 motor mount?
HELP, I"M SO CONFUSED!!!!!

Is this what you're looking for?

Yes Mike, that was exactly what I was loking for! Thanks!
Now I'm not so confused(about this one thing).
