I am building the frame for my 38 Fiat Topolino.
I have looked at pictures, read tech stuff, looked for pictures I saw once but cant find now etc, etc.

I am frustrated and at the point of hanging the rear end and I havnt made up my mind as to which way to go. So before I make that final decision as to what I am going to do, I though I would give you guys a shot at blowing the cob webs out of my head and giving me a direction that makes sense to me.

Here are the issues-
The car is short and the drive shaft will only be about 14" long from center of u-joint to u-joint.
The seats are shoved back quite a ways and legnth of links (or should I say shortness of legnths) is critical just to fit in the car.
Long angled ladder bars is out of the question, no room.
Long parellel ladder bars is not my first choice so I have eliminated that for the moment.
Given the room I have to work with a 4 link would be the best.
I have seen some 3 link setups, if thats what you call them, and that is interesting to me, here is why.
The upper links (in a 4 link) to be 15-16" long ends up into the back of the seats. (no problem with bottom links, enough room down there) and angled is out of the question (yes I can use a panhard bar)
The 3 link systems I have seen puts the upper link slightly into the seats but its in between the seats and that would work.

How important is the legnth of the upper links or link?
Can I make it work with something like 13-14"?

I guess the discussion can start here. I know its a dynamic and complex question but I just had to ask to see what you guys have to say.

Any pictures would be helpfull.
Thanks
