78-88 T-top A Pillar left hand & right hand. We built these off of NOS GM units I had. These parts replace GM part # 20373405 for Driver side Left hand. GM part # 20414887 for RH passenger side. Gm part #'s varied but the parts did not.
They are test fitted & installed. Perfect fit as expected. These are sold as sets. 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.
