will i have to upgrade the a pillars with the dash?

As far as I know they fit very close to the same way. You shouldnt have to upgrade them

lemme put it this way, i had a 97+ pillar with a 96 dash and no...it did not fit, theres the little tab for the defroster vent on the pillar in the 97+ A-pillars while the 93-96 dash has them in the dash not the pillar, if you are doing this because of the a-pillar gauges then it definately wont fit because the bubble shape in the 97+ dash is alot different

okay i was asking for a buddy who wanted to swap in a 97 dash in his 95.
