I've modified the rack extension to allow quick removal of the Thule J-Carriers when not in use. In addition, this will also permit opening the Celica's hatchback wider for easier gear access. To do so, the 1.25" aluminum main tubes are cut off about 12" at the front and back with an 8" insert ( 1.125") riveted in place. Clevis pins and key rings provide quick assembly and removal.
