Considering an LS engine swap? TCI pilot extension adapters will help to make the fit a perfect match. Simply bolting the old-style converter to your LS engine will not work without the proper spacer. TCI spacers will create the required distance, so the nose of the torque converter fits properly with the crankshaft.
