élévateur à ciseaux Porsche 356 BT6

[Jaal]

Hello all fans,
I am calling for help from France!
Sorry for my English, I use a Google translator.
I own a 1963 Porsche 356 BT6.
I just bought a scissor lift to refurbish my car.
The photo of the bridge below.
I would like you to tell me how I should position the supports without risk to the car.
The chassis is in good condition!
I would be happy if you had pictures to help me...
I'm stressed!

Thank you in advance for your help.

Place it just like the picture so it sits on the support rails (under the doors) not the pans.
