Yes. The A1418 is the model number. The EMC differentiates between different configurations.

The 2805 board is shorter and the chassis mount are in a different position.

These can be snapped off and glued to the desired position.

The SD C4 display panel has a different back light cable but will fit.

We have had issues withe C4 panel not working with other boards

Look again Peter! These are very different displays and not compatible!

- iMac 21.5" 1.4 GHz Core i5 (Mid 2014) - 2805

- iMac 21.5" 3.3 GHz Core i7 4K (Late 2015) - 2833

The Mid 2014 display won't work as it can't push 4K the newer system offers !!
