Speaker Size In Doors?

I have an 84 svo mustang, an accident a year and a half ago took out 1 of the doors and it was replaced with a 93 door, im looking to put something in the doors for midbass with a high powered tweeter in the dash, i know i will prolly have to cut the 84 door to get 1 in but the 93 door should mount right up.

what kind of depth would i be working with in the doors, i know somone has to know this?
also are those 6.5s in the 93 door or 5 1/4s? cars in storage so havent been able to check.

come on some one has to know the depth of how deep you can go? i know its a 6.5"

yea there may be some relief with high end neo speakers if i find anything decent i will post it here

or a small speaker ring could be added to raise the depth u could go , maybe a 1/4 in or so would fit without making the panel come out to far
