Would you believe that Firebird Central finally has a ship date for the re-built column. Their supplier did not find any cores at Carlisle, but did get some at a swap meet in Texas. They said I got the last one! Holy cow I knew these were hard to find but I never figured it would be this bad. They even said they may have to stop offering the re-build service since there are so few available. When this comes I can then compare it to the one I rebuilt. I need to know that the total length and dimensions are correct. I have nothing to compare mine too right now. So if you have an original 1967-68 tilt column for the floor shift- TREASURE IT!!!
