Evaporator housing

Hello everyone,

Does anyone know if it's possible to pull the lower part of the AC evap housing off behind the glove box without pulling the evap core?

I separated the 2 halves enough to spray some cleaner in there when I bought the truck a couple weeks ago but now it leaks pretty bad on both sides around where the 2 halves of the housing go together, more like sprays water on the floor and seems to be worse while turning. I think the housing is flexing the seals are bad so id like to replace them and get it seated properly.

The floor is coated in bed liner so there is no carpet to worry about but I've had to drive with the floor drain plug out on that side for a few days and would like to fix it.
