I think it is "luck of the draw" on 1954 windshield glass, especially if you want to use the stainless inserts. If you are not using the stainless inserts, you should not have problems.

The problem with the '54 glass and the stainless inserts is either that the glass patterns have gotten a little larger over the years or that the curve of the glass has to closely match the curve of the window opening (and the curve of the stainless trim). With the stainlness trim in place, there is very little "fudge-space (wiggle-room)".
