Do I need new adhesive for iPad mini logic board and battery?

A friend gave me his broken mini (shattered screen) and I have the replacement front panel w/digitizer, IC and and home button shipping. This part comes with new adhesive strips.

The corner of the unit was bent in, and the case has some scratches and marks so I figured while I've got it open, I might as well transplant the guts into a new rear housing as well. I found a rear housing for 30 bucks online. So, basically I got a nearly brand new 1 gen Ipad mini for $117 plus the fun of taking it apart.

My question is when I (carefully) heat and remove the logic board and battery, do I need to have some kind of adhesive strip ready to install into the new housing, or will the old adhesive on these two stick with a little heat and pressure applied? Also, think I'll be able to reuse most of the old tape if I'm careful?
