Parma Euro Panther project

[V12]

I will have a Parma Euro Panther project through the winter. Not restoring an old car but building a car from parts, again.
Got a prototype chassis and some special parts but there are lots of missing parts also. Have an exploded view drawing but dimensions and part # are unknown. Someone have a manual, if there was one?

Some questions on hardware, what size/type are screws and nuts used for front end and t-bar?
Also what size is the brass (?) ball used at the ballcup for the center dampener, the one which uses silicon tubing. Have that dampener but the ball is missing.

The nuts & Screws are 5-40 thread.
