1970 GTX Brake light switch

Which switch do you guys have on your 1970 B-Body? I am also having difficulty installing the bracket with switch # 2. Does the bracket go into the top 2 holes or the bottom 2 holes out of the choice of 4.
First type
Second type
Pictures would also be helpful. Thank you.

Type 2 on both my 70 B bodies.

If you get a chance 70 gtx440dana could you please look and tell me if you bracket mounts into the top holes or the bottom ones. Thank you.

Just a hint...
Mount the bracket 1st then install the switch to the bracket..

Just my $0.02...

I tried that method and then could not get the switch to push through the grommet. Now I'm having a hard time tightening the single bolt. No room and extensions hit the heater box.

I got it in! 2 3" socket extensions with a universal between the 2.
