Chassis dimensions of 73 duster

[Cythomas]

Can someone help me tell what point B is on my 73 duster I’m installing new front frame rail and measurements should be taking at point B

Hard to tell. Maybe its one of the bolt hole locations on the k member where the steering gearbox mounts or the k member drivers side rear bolt location

2nd picture shows point b. Thats definitely the drivers rear k member bolt hole location on the rail

My best guess is the center of the spring adjustment bolt. Hard to tell without the legend. Technically it should have a circle with a line through it to signify the center of a bolt.

Both a and b are k member bolt locations. Im pretty sure tho. A is clearly marked and it lines over to b

No legend I wish I got the picture from the service manual
