I have a few...I pull one out of any car that I know is getting scrapped...how are you adapting the base to the car seat? I have been using 1/2x1/2 angle iron across the rails and pop riveting the whole thing together. I have all the functions of the office chair base and the adjustability of the car seat. » 2/06/15 4:28pm 2/06/15 4:28pm
