M1113/4 A/C Help

I'm installing a hybrid A/C system in my M998 consisting of the evaporator and dash duct from an M1113/4 series truck and the wheel house condenser from an M1151 series truck.

Can anyone share pictures or describe in any more detail the radio tray mounting brackets? I can't even find an NSN on them. The existing ones in my M998 are smaller and shorter because they fit inside the old style heater duct. The A/C duct is much bigger and requires something different. Do the M1113/4 brackets replace the M998 brackets? Or do they bolt to them?

In the attached photo they are circled in red but the detail isn't great.

Also I'd like to know what the square connector piece that goes between the dash duct and the blower motor is. Is it just a square steel hose clamp? Or some custom plastic thing?

These are the only two pieces I am missing.

for brackets, I see...
12460542-2 (2)
4660716 (1), LH
4660717 (1), RH

I can't find individual pics of these though.

The big square clamp is 70-04738.

I'm looking for the ones in the picture. My M998 has different, smaller ones than the ones in the picture.

Those ones in the TM maybe bolt to the ones in the picture like you said.

Thanks,
