Hi, wow, big swap, but possible! The coupe and sedan dashs are interchangeable, but model specific(L,LS.) The A/C controls vary
with model also. This post attempts to answer the airbag issue.
If you change the dash; the wiring harness dictates the components.
If the new dash has a passenger side airbag, you have a choice: same
harness, no airbag; or, new harness to include airbag. The AC and radio
may also be harness dependent. Staying model specific (L,LS) may be
easier in the long run. Keep posting, there are many details and many who can provide insight, Remember to use search function. You will find the HELM
manual very helpful: get one that matches our model nd year. I will stop at
this point, except to ask if you might have a friend who can help. Keep
researching, obtain HELM, keep posting, plan and just do it! Good luck.
