Thanks guys! I have a lot of options to consider! I don't have the original seats or mounts unfortunately, so I will end up buying or fabricating mounts in some capacity. I'll be stealing the engine out of an S10/Blazer/Jimmy, so I'll possibly have those seats at my disposal depending on how good of shape the vehicle is in. I don't particularly like the idea of sitting directly over a bunch of gasoline, but I probably won't move the fuel tank, and I like the idea of keeping the tool box there for originality and for practicality/storage. I'll have to play around with the mount options when I get there. I'm currently getting my frame prepped for primer and paint, so I have plenty of time to do some more research and thinking before I need to start making decisions. I do like the JEGS option.

I appreciate the information! Thank you all!
