Lookin good so far! Yes, it is an old kit that has had went thru some changes, but as you are finding out, it turns into a really nice kit with some work. You should have no problem with the interior on this one (I did the same on mine). It is probibly a little late, but with the frame getting so rough in the later releases, you can swap it with the Boyd Smoothster versions for a more updated chassis and better stance.
