How possible is it to pull the dash out of an `87 Integra LS and drop it in an `86 Civic Si.

I know tons of other parts from these cars swap.
(I recommend if replacing headlight/wiper/signal switch get the 5dr Integra's switch and little rewiring and all good. And the switch feels much stronger, grab steer wheel too and you get 2 buttons (if cuise control) on wheel to wire up to what you want)
