Over kill or just stupid? I decided to replace the cheesy transmission cooler that was bolted to the front of the K frame with the heavy duty B&M unit. All the lines one of the previous owners installed were leaking. I didn't feel like laying on my back bending steel line all day. Sooooooooooo I measured them all up and had 3/8 double steel braided, 4000 Lb burst strength lines made. I think they will out last the car.
