Okay everyone here it is I thought I would make a thread with "MadDart" 4 Link rear. I asked him if it was okay and he said sure, so here we go. This is what he PM'ed me so it is as if he is posting this to all of you.

That is pretty much it. You can contact whynotfab.com , create a user name and let Ricky know what you want him to supply. He will take care of it and you will have your link set up in a few days cut to your spec's.

Part 2

More........

I will do a follow up on measurements etc. It will take me a day or two. One problem I see is if your frame rails are different from production flaws it could end up wrong. Also I used a B Body Housing so my measurements would be based on them. As you start to put it together it makes more sense as an as Built Project, that is how I did mine anyway. It took me about 20-25 Hrs total to mock the whole thing up.

The pieces for the Link Boxes are as follows.

The finished product is 3 1/16 inside box measurements by about 12" long to catch a weld across the existing frame on the radius point.

4 pcs 5" x16 Fine tuned to fit
3 pcs 3" x16 Fine tuned to fit

I followed the frame rail by just clamping the first piece in the cut opening of the rail and using a scratch all to mark it. As you can see in the picture I held it down some and radius'd the edges to cover the bushing completely with the Plate. Most guys dont do that but I wanted the whole bushing to ride on material and not air. I used the hole in the existing frame rail to set the first link mounting hole and split the measurements I think 1 3/8's apart or whatever makes them the same distance apart, and I built them IN PLACE, not on a bench.

Cool thing is, I believe Hemi Denny Will be making 4 links for mopars soon
 
I have that 4 link in my car now and can tell you that it's built quite a bit more beefy thanman RMS setup. My only complaint is the nuts tend to loosen on the link bars and is about impossible to tighten some of the nuts if the bars are still attached due to space constraints. I haven't devised a way to lock the nuts in place yet.
 
I was planning on doing this conversion but Ricky and WhyNotFab no longer exist.

Does anyone know another source for the parts, especially the tabs that Ricky made?
 
Does this set up come with a panhard bar? The link provided, those upper links don't look like they are at a wide enough angle to completely eliminate side to side movement. What are the angles you mount the upper links at?
 
Just if anybody was interested, the info is still here...if this is against the rules of the forum by god I will delete it as so not to bother you with this BUMP. Let me me know and I will take it down...ask me how many F'n PM's I used to get on this subject so that's why I made this thread. But I guess 4links are out of date and the youngsters are on to bigger and better things. :)
 
I didn't build this...I only asked MadDart for his specs...I was the only one who saved it, That's why I put his build thread in here so you could ask him. Everyone wanted his build specs and kept on PMing me for the build specs so I posted them here. I haven't built this so I can't answer questions nor did I come up with the build specs. What's your question so I can't answer it and you get even more pissed at me....Just the messenger here and thought the build was still relevant so THAT'S WHY I BUMPED IT sorry for inconveniencing everyone with this little BUMP.

Thanks for bumping this. Was looking for info on 4 links but didn't remember who posted it...thanks again...
 
wow blast from the past...

find sources for what?
Whynotfab.com is dead and the links for parts from jegs are also dead ends now.

If I get some time to just sit down and scour the web, I know I can find everything needed for all this but I figured I’d see if anyone happened to have current links/sources for everything needed in this parts list.
