Add notes:

All parts from 88-98 are interchangable with one and other. This means that all parts in the 88-94 style interior WILL fit into the 95-98 interior and visa-versa.

Tech notes:

98 dash install: All three bolts on top and the top on bottom line up perfect. The a-pillars and kick panels also snap right into place.
