I'm actually looking at replacing the entire evap cabinet assembly (fans, cabinet, coil etc.) with a late model unit to increase the cooling capacity.  I just haven't been able to find any comparison of sizes to estimate the increase in BTU capacity.  The late model has dual, larger, fans than the early single motor, dual squirrel cage system, but coil-wise it's a little nebulous.

 If you are looking to
 replace it, there's an aftermarket improved alternative.
 You should be able to find it in 2014 archives.

 1987 Westy A/C evaporators?  Curious as to the size
 increase of the post '86 coils over the earlier ones.
