New Suspension Project !
Ok guys.... my job is to produce Laser Cutting Systems !
So for me is easy to cut parts in steel in very strange shape..... and now is te time to modify the rear suspension of my C3 Corvette!!!!
Following some screenshot of the project (the parts are allready cutted and I need only to weld together everything):
Rodends are coming from Vettebrakes (3/4").

oops....
...hehehehe..... you are right! 
This is a Modified C3 Rear Suspension..... you belive?
You will have:
Lower Arm....
Upper Arm....
Toe-Control Arm....
Double (C4 style....) Trailing Arm !
In a few weeks I will let you know if the car will handle better..... or not!
.... I know...... my English is Tremendous!

I think it is a great idea, basically this will allow for good toe control and provide an upper link.
What kind of stabilizer bar are you using with it. I would make something that can use most aftermarket bars with horizontal eyes.
What kind of springs ? Original ?

Yes..
The leaf spring is from VetteBrakes and have a ratio of 360 lbs,
Bilstein shocks and the stabilizing bar is very thin..... two options:
5/8" or 3/4"
As Herb Adams suggest, you must be very "flat" in the front and quite "free" in the back.... for traction coming out from the corners!
As you can see in te pictures, there is a prevision for connecting the bar with rod ends.
The upper arm and the toe-control arm are connected to the differential through a plate bolted in the two upper holes and 4 (2 left - 2 right) side holes.
The short heads bolts are perfect for this purpose!!!!!!
I see you are from Belgium and you own a 1979 Vette....
I'm from Italy and I even own a 1979 Vette... plus a 2006 black C6 !
Last..... is someone likes to reproduce my project, I can send the cad drawings (DXF or DWG) of all the parts except for the rods!

I can see that it will not be that easy to reproduce the hub without the necessary tools.
I would think that if you can keep this at a reasonable price and can produce a comprehensive package, you would be in the market real soon.
Let us know

Some other question, as far as I know the pivot points should be in line and forming a perfect parallelogram. I would keep the most rearward link parallel to the half shaft and the pivot point of this link at the same place as those of the half shaft.
Also I would not place the front links parallel. I assume these would need to intersect at some distance to form some kind of swing arm, maybe help in creating some squat properties. TT could help you out on the right design, he's the expert, give him a pm. Just a thought.
Price... you want me to give you a price ? Give me an pm and we will discuss this further.

Links
Yes..... normally the links are parallel, but is not mandatory!
Remember that the relative position of the links result in the position and the legth of the "swing arm"..... in relation to the groud!
This is a very important aspect of a suspension project.... a to short swing-arm will result in a severe "jacking" issue during hard cornering !
Regarding the shaft, I will remove the C-clip..... but in the future I would like to found a good supplier for sliding-shafts !

Squat...
No way to build a significative amunt of Anti-Squat in IRS rear suspension!
The torque-reaction is confined in the differential and you can only put a bracket between the diff-housing and the frame.
Othervise is very simple to build anti-dive in order to avoid "brake-hop".... as yo can see there is several holes in the rod-housing in order to adjust it!

Because of my previous searches about rear suspension changes I seem to have found a firm in Belgium that is able to do the slide shaft setup (had them take a look at a spare set that i have). Not the most cheap change you will make (ca 800 €), but very doable and being nearly the perfect solution to the half shaft issue.

Thanks...
Thanks.... but I think is possible to found some people doing that even closer to my home! 
The most important aspect, I belive, is the balancing of the shaft..... after the modify....
