1957 cadillac

[60eldo]

  Can anyone tell me who know 57s, if the chrome boomerangs on the back of the car above the tail lights are the same length cause when I put them on, when I lift the gas tail light door it hits. Seems the driver side should be shorter  by about a 1/2 in.  are both sides the same, can anyone say

Those moldings are called "Rear fender crown" and are the same for both sides. There is however a difference: models 6039X, 6237, 37DX and 67X have the kit number 3631982 (1 for each side) and models 6239, 39DX, 7523X and 33X have the kit number 3631983. Maybe you have a mix. Look at the casting number at the back side, it must be identical. If not, something is wrong.
