I would just leave it. Seems like on a car like this that it would be a PAIN in the you know what to chop. If you do decide to chop then nothing more than 2 inches. I have a 48 Chevy Coupe and I was going to chop it since it was as about high as yours there but decided not too... Someone said on a 48 it's way too hard and I would need to have a lot of other metal to reform the back section, etc and also it's a coupe and doesn't look real high anyways. Two tone the thing with a light color below and a dark on top and that will make it look lower. I agree on the bagging too!
