Trying to get a '73 Barracuda on the road after having it for 10 years.In need of shifter rods and levers, found a used set off a '70. According to Passon Performance there is differences. Can anyone tell me if it is interchangable or do I actually need a '73 setup? Trying to scrap pennies to get the car on the road, so buying a new setup is my last resort. Thank you all in advance.
