Help! Front brake caliper bracket id

[Vr4door]

Made a stupid mistake and mixed up the front brake caliper brackets and they are identical, except for on the back side one has a 3 and the other has a 4. Does anyone know which goes where or can someone please take a peak at theirs and let me know. Thanks!!

PartsBase.org lists them L+R, as the same part number, meaning they can be used side to side.

51054L MB618218 SUPPORT, FR BRAKE CALIPER, LH. Period: 1990.06.1-1992.05.3; 01
51054R MB618218 SUPPORT, FR BRAKE CALIPER, LH. Period: 1990.06.1-1992.05.3; 01

So, they appear to be 100% interchangeable. Also used on the following vehicles:

3000GT (MMNA) [Z10#] 1990-1999
3000GT (PUERTO RICO&GUAM) [Z11,16A] 1990-1999
DIAMANTE (MMNA / MMAL) [F16A] 1991-1996
DIAMANTE (P.RICO&GUAM / MMAL) [F16A] 1991-1996
DIAMANTE WAGON (MMNA / MMAL) [F07W] 1992-1994
ECLIPSE (MMNA / MMNA) [D20#] 1988-1994
ECLIPSE (MMNA / MMNA) [D30#] 1994-1999
GALANT (MMNA) [E30#] 1988-1993

Just be sure to confirm the slider pins are identical and that they move freely when inserted and with pads in place/bolted up the the calipers. As long as there is not drag and you can wiggle the caliper in/out some, you should be fine at that point.
