So this cabinet doesn't even have a proper bass reflex port. The horn is only bolted at the top of the cab with two bolts, the bottom of the horn is just floating. The entire horn opening IS the "bass port". Wow. I have some work to do. It's scary how good these are going to sound.

BTW, I pried the LF driver from the baffle. It just had 40 years of surface tension holding it on.

You can see in this pic that the horns mounts on to the light wood on top. There is a 3/4" gap on the bottom, plus the gaps on the side. Woof...as they say.

Here is the horn with a piece of 3/4 MDF inserted:
