Please tell me I got the right spotlight

OK so I got my packages all delivered and unpacked. Hoping this will all work for my 1962 Suburban. Everything looks really good, mechanically sound and really crisp and clean but I am hoping the brackets will work.
In my package I got the light with the GM logo with internal bracket, an extra separate bulb and a 31 outside bracket with gasket and the needed extras. I told the guy to make sure to send me a 31L so he followed up another package with a 2nd one that is titled 31L which included the gasket and does look different than the first.
My question is do I want the 31 or 31L and does my internal bracket look right? The photo with the small manila bags are for the 31 and the photo with the grey Unity box is the 31L.
Thanks,
AJ
