Not sure yet, Jason (camaro13z28) says to use a air hammer with a sheetmetal cutter on it to knock out the ribs. Then use a sawsall to cut down the main section. Then clean up with a flap wheel. I will try his method first. I thought of just buying some pvc ones to avoid this part but I guess I'll give it a try. I'll keep you updated on the fireworks. Oh and I'll be saving a few pieces to toss in the bonfire.
