Did anyone have to cut the rubber weather gasket to fit around the tower? The repro one the hole seems rather small? Are there any pics or diagrams of this assembly?

It's just a generic aftermarket hunk of foam. Cut as necessary to fit.

A few things going on:

1) The Foam goes between the transmission and the underside of the floor (Under the truck).
2) Ford had different part numbers for the 3 speed and 4 speed. The offering out there today from DC uses a Ford looking part number that I can't find in my Ford library.

What does this mean? You have the foam you have - I'm not aware of any other options on the market. You can adapt it to you needs.

You can see here a related discussion on an F4: https://www.ford-trucks.com/forums/1...l#post21329573
