I recently inquired of these costs on our fordor, with an upholsterer in the area who is well-known for top and interior installations on both Model A's and classics as well. I was told that he would charge roughly the cost of the interior kit if I provided one of the LB kits, or he would make and install the interior if I provided the materials, for roughly $3,000 - $3,500, exclusive of carpets. However, I have a friend who installed the headliner and interior panels in his 1930 tudor and did an outstanding job. He decided to have LB install the seat covers on his seat frames and springs, but was very satisfied with both the price and the quality of their work product. I believe that I was told by one of the ladies in LeBaron Bonney's service dept. that their hourly shop rate is $70/hour, and that it would take the better part of a week or so to install one of their kits in our fordor. Hope this helps to give you an idea. Good luck either way!
