SSO Slimline light bar question

Hey all.
I just picked up an SSO Slimline with the 20” Rigid light bar cutout.

Anyone know what the difference is between the cutouts for the different lights?

Also, anyone know what other lights will work in place of the Rigid SR20”?

Thanks in advance.

 

Could probably just figure out the dimensions. Use a spacer if it's slightly shorter.

 

I think different light bars have different shaped cut outs, not necessarily different dimensions. I'm just speculating tho and don't know for sure.

 

Thanks for the input.

I called SSO and they said the Rough Country single row also fits.

I’m just gonna go with the Rigid.
