Marty,
Thanks for the information on the studs. I'll dig out the old measuring tape
and see if the Dorman studs will get the job done. Please thank Seth Emerson
for me. This will bring me one step closer to finishing up the V8 conversion
that I've been workin on for about 15 years.

I recently installed a set of front disk brakes that I bought from Clarks a
few years ago. When I re-installed the wheels I found the front lug studs to
be a little short due to the thickness of the rotors as compared to the
drums. I contacted Clarks and they only carry the standard length studs. Has
anyone else had the problem and if so, what studs did you use.

How much longer of a stud do you need? Dorman Products 610-157 is 2 1/8"
long and will fit Corvair hubs. You can get them from Amazon in a package of
10 for $16.51 plus shipping. Thanks to Seth Emerson for this info.
If you need longer studs, I believe Moroso makes some, I have the part
number on another computer.

I'm not sure my site still shows my initial attempt at a four link rear end.
I abandoned the plan when I priced the required half shafts with
slip-sleeves and the fact that my 930 could easily deal with the side loads.
In your case, I assume the Renault transaxle can't take the loads and you
need to build a fully isolated drive shaft arrangement. I don't have a lot
of advice, but here are some thoughts.
1. There is something you can attach to. Build custom brackets to attach
the upper arm to the UN1.
2. If you really can't find an attachment point in line with the drive
flanges, then consider a cage attached where you can. Then attach your
upper arms to that. You can see that I sort of did that for my lower arms,
which may give you an idea.
3. Also look at my pictures of Arch Evan's SuperVair kit, which builds a
box/cage mounted to the frame and the transaxle fits into that.
4. Geometry is tricky. The travel is an arc, so you always want both arms
parallel or higher at the wheel. This avoids positive camber at the
beginning of the travel. The degree to which your arc creates negative
camber is math I don't know, but I applied a basic assumption that seemed to
work. If you make the distance the same from the center of the drive shaft
to where both arms attach, on both ends, you have a perfect parallelogram.
Now, build your mounts so the upper arm is slightly shorter (I think I
picked an inch shorter). As the travel moves up, the shorter arm follows a
shorter arc and creates negative camber. Someone better with geometry may
be able to give you better guidance on dimensions to get specific camber.

By using cv half shafts, I am aware of the need for an upper strut to handle
the side loads. The transaxle(UN1) does not have suspension mounting points
so will have to attach everything to the cage/body member. Could those of
you that have tackled this problem share your ideas, what your did, what you
would do different etc. With the need for neg camber gain, I find this a
bit confusing.

So Jim - I guess that could be described as the Acker-man effect! (grin)
I would be interested in a graph of the actual camber as it goes through
the full up down travel. But I don't quite understand. If you are running
fixed length driveshafts, why are you running an upper link - or are you no
longer running an upper link? Also a note, the shorter upper link will
provide increased negative camber under droop as well.
