I just got off the phone with Putt Georgi, owner/president of ARO Convertible Tops & Glass
out of Walden, NY. I had heard in another thread that they were producing "tonneau-style" soft tops for Broncos and decided to investigate.
Mr. Georgi advised me that ARO is currently making two styles of soft top (click here
): STC/Fastrac style and "Fastback." The Fastback runs about $395 in vinyl or a little extra in Stayfast Cloth. The STC style is $1500-$2000, depending upon whether or not you want a bolt-on frame rather than drilling holes for snaps. At this time, a bolt-on frame is not available for the Fastback tops. That was something that soft-tops.com had produced, but ARO is in the process of finding a machine shop to make a similar setup.
Each top is made-to-order, and they can usually crank out a soft top in 2-3 business days in any color you want, with clear or tinted windows. Since each top is custom-made, you have the option to add extra windows (Fastback), etc.
Another interesting thing that Mr. Georgi told me is that ARO has always produced the Fastback tops for soft-tops.com, who went out of business about 6 months ago. He has been trying to contact them, but no luck so far.
