Help with measurements

[911S PORSCHE]

Hello fellows pelicans , I am in need of some help.
I need some measurements like how to get a center line, and from that establishing a reference point under the car to measure the rear and front wheels to get it squared, just like we have seeing on how some people do their on alignment.
1976 PORSCHE 911S with SC flares front wheels are 16X6 and rear are 16X7
Thanks Cesar

Your dimensions will be the same as for an SC w/ stock 6 & 7 x16 wheels

front track is the distance between the center lines of the front wheels - 1361mm
rear track is the distance between the center lines of the rear wheels - 1367mm

It's really easy to check your own dimensions, I use 2x 2' x 3" pieces of wood. The exact dimensions are not critical, just long enough to fit next to a tire w/ enough extension to measure from and tall enough to fit solidly against the inner and outer tire sidewalls w/ no rocker, too short in either dimension and there will be error from the wood rocking
