Classic Jauguar in South Austin has these. They are very nice.....and they tilt. http://www.classicjaguar.com/buckets.html
Already thought about smacking the windshield but the top of the seat actually stops on the header above the windshield, might still need some type of cushion in that area to keep from scaring up the edge protector material although it seems to be plenty tough. There is no way to lower the pivot point because of the way the seat sits on top of the adjuster. The only way to get it lower would be to cut down all 4 legs a little which would mean all 4 of the drivers seat legs would also need to be cut down so they will still be level with each other. That option is still on the table Tim, but I am kind of lazy and if I have to cut something the 1" square tube it is barely touching would be alot less work. With the tube brace gone or moved a little it adds at least a couple of inches if not more to the height in that area. But then there is always the headliner issue if I decide to put a liner in it at all. I am not that good at thinking ahead which has caused me numerous headaches already. Might have saved myself some do over work if I had lowered all the legs on the adjusters to start with. The rear legs had to be fabricated anyway so I probably should have just cut off the front ones also but I didn't really think about how far up the seat would rise when it was tilting forward. I am waiting on the padding for the cushions to show up so I can stick it in one seat and see how much head room is left. Anyone over 6 feet tall will have hell riding in the car but I should be ok. If there is not enough head room left I will still have to cut of the legs. I am hoping a couple of inches left above my head will be enough to keep the knots off my head after hitting pot holes in the road because I am sure with the coils in the back and considering how light the car will be there will definately be some bouncing around from time to time.
Those look like a good option Moter. They will fold forward and then could be made to tilt, and that would get them even farther forward for more access room to the back. I was going for a more raw look with the aluminum but if I had seen those first I might have chosen something different.
Actually, after looking at that frame I would think a first semester fabrication graduate could duplicate those with simple hand tools a bandsaw and a 110 welder. Frank
