Should I buy a eta 2836 or a 2824 mvt

[horologist]

I have a water damaged replica submariner which has a rusted mvt and would like to replace the mvt.  It has a eta 2836-2 mvt.  I also have a spare dial and date wheel overlay, but am not sure if it is recommended to get a 2836-2 or a 2824-2 so that I can fit the date wheel overlay without any hidden problems??  I heard rumors that the 2836 Is less problems for this than the eta 2824 but don't really know why.  I am very ignorant about this and would appreciate any feedback to which direction I should go???

many thanks in advance

If the current movement is a 2836 then replace it with a 2836. If you go 2824, you will need to swap some parts and come up with a dial spacer to make everything fit properly.
