Here's a fantasy build 71 Challenger R/T

-E74 Hemi
-D21 4 speed
-FJ6 Green Go
-VJ6 Lime R/T stripe
-N94 T/A hood
-M51 Sunroof
-V1X Black Vinyl top
-A22 Front and rear rubber bumpers
-A45 Front and Rear spoilers
-G36 Painted Mirrors
-A44 Rear louvers
-H5F7 dark green with green hounds-tooth interior (not recommended/ with FJ6 or not allowed?) If not H5XX Black Hounds-tooth
-A33 Track Pack
-B41 Disk brakes
-S77 Power Steering
- Tuff Steering Wheel
-R36 AM/FM with cassette
-P31 Power Windows
-J41 Pedal drees up

Second variation on that would be with EV2 paint, Orange R/T stripe, and orange hounds-tooth interior.

*No rocker panel, door edge, or A46 molding group because it's busy enough looking allready. It would break up the "painted out" theme.
