question

this might be a really stupid question but im not sure of the answer. If i were to put body kit and exhaust on my car, then say a year down the line do an engine and trans swap will i stil be able to use the same body kit and exhaust. Im pretty sure i will i just need to put my fears about this to rest.
Thnx,
like i said, stupid question

Oh but also would there be anything that would be affected by the swap? besides the obvious things.
