2 door hardtop 23 model side and upper windshield trim is different from a 4 door 41 model or 2 door post car 21 model. The lower piece is the same for 21, 23 or 41 model. The side pieces from a 21 or 41 model can be shortened to use with a 23 model but the top two pieces from a 21 or 41 are shorter in length than a 23 model and will not fit correctly
