Finishing my dad’s custom 65 barracuda

You said it looked to be 4 inches higher than the tire, keep in mind that those rear wheel wells are modified so it makes it look a little higher I think since the factory rear quarter panels covered up about 4 inches of the rear tire, but it looks nice and they did a good job, that’s a hard mod to pull off. What size rear tire are you running? A lower profile rear tire would lower it too without changing the suspension
