For a gen 1 you can buy it right now. E mail or call Steve at Autoform if you would like the original AF double bubble top style with the "fastback" look. like ILLKNG has. For gen 2 owners the fastback/coupe look is still in the works. But it would be based more off the new style top from the rt10 hardtop market thread instead of the classic double bubble. So a quick breakdown...
Available now, for gen 1 original Autoform roof, original roof with fastback/coupe style rear section, and for both gen 1&2 the new style AFR top.
In the works is the gen 1&2 new top from the "rt10 hardtop market" thread with a fastback/coupe rear.
