Can anyone tell me if there is a difference between a power and/or manual drop top frame? My convertible Challenger originally came with a power top, but the previous owner chose to convert it to a manual top. I am seriously considering going back to power, but I'm not sure if the top's frame I have on the car is unique to a manual drop-top. I would be looking at after market pump, cylinders, hoses, etc. Any help would be greatly appreciated. Thanx
