Look's very good Jay.. But I think they should make the post bolt into the car like I did mine.. Have the whole floor glassed into the car.. Then make a plate that weld's to the frame and the car's floor sit's on the plate. Then the weld a plate to the bottom of the door post. then bolt it to the floor and through the frame plate.. Then you don't have a post welded to the frame and can't remove the car later if you need too. Not trying to put down your work Jay.. Just trying to give some help..

I still think your doing a great Job Jay..
The front frame under the dash,Can also be done the same way..
