Kody,
I don't want to sound like a know-it-all (god knows there are enough of those around here) but you should compile a list of some of the mods you like and then perhaps post ur list in the swap and sell letting people know that you are looking for those particular mods.
Take a look at some members' rides and find some things that you'd like to buy for your trac. You may find it helpful to email members directly to ask any questions you may have about their parts. I had a guy emailing me quite regularly about the spacers I used to make my wheels stand out a little bit and I helped him as much as I could.
If you are new (I dont recognize ur name), you can check out other members' pictures by clicking on the file icon beside their name. If you want to see information about their truck you can click the icon that looks like a person standing in front of an 'M'
Hope this helps.
There are hundreds of things you can do to your gen1 trac so its completely up to your own personal tastes as to what you want to do. Another good place to start is by clicking on the "sponsors" link on the left hand menu. They will have a bunch of parts for you to check out too.
Goodluck
