I have replaced a dash and it is not difficult, just somewhat tedious. I
am unsure whether the heater core replacement requires complete dash removal.
The lower right dash and glove box might be enough. Someone more experienced
will know. Online service manual section 21 deals with blower removal.

Heater Core Replacement?
Edit: see Ari-ones post below. The '91 and '92 legend have R-12 freon unless converted. The refrigerant will need to be captured and re-used
unless you or the AC service have access to R-12. Otherwise, the AC system will need conversion. In another post, the core was priced at $350-$400 with installation at about $550 for a total of $950.00. I do not know how accurate that is for your area. Acura of Augusta or Delray can
provide a quote for the core. That is all I can offer. GL 12/27/10
