Gen3 hemi tkx swap

Update. It’s running and driving! The car is very fun and pulls hard. Need to make a real shifter lever and boot for it. Gear mesh noise is kinda loud without one along with the heat.. I’ve never had a manual car before so I’ve had to get used to using my left leg for the clutch. Little jerky at first.. the car is very fun and can wait to hammer on it after the break in period.
