new carpet after bodydrop?

Truck is bodydropped, 89 mazda ext. cab and have real shitty carpet in it. I'm wanting to redo the interior and while doing so, soundproof/heatshield the floor and firewall area and put down new carpet. Will factory carpet fit or will I have to get someone to do it?

Pretty sure you can just get factory carpet but you want it untrimmed so that you have more to work with
