78-88 T-top A Pillar left hand. These were built these off of NOS GM units. This part replaces GM part # 20373405 for Driver side Left hand. Gm part #'s varied but the parts did not.
They are test fitted & installed. This is left hand only. This should be left to some one with welding experience & professional body work experience. The a-pillars can also be cut & re welded back in as to not replace the full length. So if you have a T-top car that you think is too far gone it no longer is.
