Who and where should i buy a new top for a 69 barracuda

I just bought a new top from Restoration Parts Source, with new back glass window. Price was about $440. Had to buy new pads and cables separate though. I have lowered my top hundreds of times, no need to unzip the window, I have never has a problem, I do strongly agree not to put anything in the well, keep the well liner in, and store the boot cover neatly in the trunk. Hope this helps.
