Lower Control Arm Shaft bolt

[Tac]

Hi,
When restoring my -57 custom 300 I saw that the former owner misplaced the long bolts for the lower suspension arms.

If anyone has any info on the dimensions or a blueprint for these as they seem easy for me to make at work.
We do things like this all day long for Volvo trucks etc

The cost of buying them for $ 200 is better placed on other parts wich is also misplaced by former owner : (

Please let me know if you have any information regarding tolerances or any other info regarding this part : )
