Luckily I found a way to know whether I needed a Valeo or Denso evaporator without dismantling the dash.
Technically, you should just replace the receiver dryer given that you’ve had a leak and probably have depressurization the system at this point.

That said, given that it appears to be integrated into the condenser, it’s probably not worth worrying about. Just swap the evap and pull a vacuum on the system immediately. (Don’t wait to reassemble the dash - you need to make sure that it holds vacuum before you put it back together. Yes this means that you need to buy a vacuum pump and a set of gauges.)
