Best next upgrade?

Never heard of "Trak-pak" on 69's?
A53/Formula S yes.
Care to share pic of fendertag?
one thing that i learned the hard way was that even though this is an "A33" fender tag car (Track Pak w/3.54 ratio) it had a 7-1/4 under it when it showed up. I decided it was still worth buying but had hoped for better...
