The things I see different from my L4:
1. Old style reactive caster blocks
2. Old style front end brace, with shimms for adjustment
3. Reinforced servo saver with ball studs on other side of servo saver opposed to stock
4. Servo glued flat on the chassis
5. Aftermarket eyelets
6. Ball stud raised for improved ackerman. Just look at how similar those front wheels turn! That thing must be efficient!
7. antenna mount turned, probably for more room for the receiver. Looks like a lot of CA went in there! O-rings, probably to avoid play.
8. purple ball stud with O-rings.
9. 4-point upper deck
10. aftermarket left clamping hub
11. dremeled T-bar
12. modified, or even custom-made radio plate
13. ball studs for tubes?
14. Lowered pod plates
Did I miss anything?
Oh yes, a top noth driver behind the wheel!
