How hard is it to change a starter in a 340 Duster?

I’ve been working on my 340 Plymouth Duster for almost a year and I’m pretty sure the only thing stopping me from cranking it is the starter. I will be removing the old one and installing the new one tomorrow and I’m wondering how long it will take and how difficult it will be. I’ve never changed a starter before, but there’s tons of resources online, so I don’t think it’s going to be too hard. I am just worried I’m going to have to take a bunch of stuff off to be able to remove the old one. Thanks!
