brake booster

Somewhere I read a post that said you could swap out the pwr brake booster on a 89' to one from a 90' and improve your braking.Anybody ever done this?

It should be a 95 or later booster, that's when the change from a single diaphragm to a double diaphragm happened.

I installed the 95 booster and master cylinder on my 94. It was a worthwhile change.
