Goodman cased evaporator installation

Need a little (basic) information regarding the installation of a Goodman cased evaporator. I'm pretty familiar with furnace installations, but because I only (briefly) worked in residential HVAC in a cool climate, I never really got any A/C installation experience.

My question is this: In an upflow situation, how do you guys attach cased evaporators to the furnace below, and to the plenum above? The evap drain pan is uncomfortably close to where I would expect to screw casing to furnace. In certain manuals, I've seen that the evaporator "doesn't need to be anchored with screws". I've also seen a couple videos where guys just lay a bead of silicone around the connection between furnace and evap.

Similar question when attaching the plenum to the top of the evaporator casing. The Goodman evap comes with some odd sliding lip at the top of the casing, but each sliding side is only held in place by one screw, so there is some play in each piece...not exactly an easy thing to screw into when trying to set screws from the outside of the plenum.

Anyone familiar with Goodman installations? Any tips, preferences?

Thanks...

Don't know Goodman (low end) but normally a cased coil just sits on top.

Thanks, Airman. What you said does seem to be a broad consensus.
