I have no idea why the GM rear end? It's what was available I guess? The guy I bought it from said it was a 3:73 posi? I'd guess from a camaro or S-10.  Mind you even if it had the AMC rear end I'd still be changing it.  AMC rear ends are kinda goofy in that they had  a hub that was held onto the axle with a big nut and a type of wooddruff key . 
Now my minilite style wheels will fit.
It was about the same temp here too. Yuck!

Have you considered sliders to replace the shackles? I read they lower the rear a smidge

I've seen those. Used often in circle track but I'd rather use the stock type shackles . This car is already going to be a magnet for law enforcement/MTO I'd rather not give them more to be concerned over LOL

AMC model 20 rear ends aren't the most performance oriented because, like Brad said, it has a single nut holding the axle and hub together. GM rear ends are plentiful and inexpensive to build out.

Had a couple hours today to spend on the Javelin so I went over to my buddy Mikes place and installed the new stainless diff cover and my 10" drums that were on the Challenger when I bought it. I picked up new leaf springs today and shackles from a B-body Mopar ( they will work in the Javelin also)    I sure like Mike's Charger! He has very good taste in cars!  Plan is to install the rear end on Saturday, should go quick.

[Brads70]

Well its in for good . FYI a 67-70 Chrysler B-Body rear end will bolt right into a 71-74 Javelin with zero modifications . Maybe u-joint /driveshaft issues? but I'm getting a new drive shaft anyhow so it's a non issue in this case
Mike and a I installed it in about an hour along with new leaf springs and shackles . Only hiccup was the locating hole for the drum brakes needed to be opened up  .050" thou or so to fit on the Strange S60 locating boss on the axel. I was happy/surprised also that the stock E-Body
e- brake cables bolted right into the stock set up from AMC. Nice when things go easy and you get to reuse/recycle parts!  New leaf springs kinda disappointed me in that the bushing was about .160" to narrow on each side, making it sloppy fitting. I quickly turned up a washer/spacer. I'm glad to have the lathe and mill in my garage, sure comes in handy! Seems like all resto parts have issues not just Mopar stuff.....

That looks great. I like to build things to accept factory type parts as well. For instance you can throw a stock 8 3/4 in there anytime you choose with no fabbing at all.

Awesome , you won't be breaking that !!

[Brads70]

Well it was just over 50 degs here today , so I sprayed the engine bay.  Turned out ok got a few runs but mehh its and engine bay.  Now I have no excuses to not work on it. Running new brakes lines next that I got from Inline tube. They made a kit to do the whole car .   Then I guess its engine install time. That will be nice as it will free up some space in my garage.

[Brads70]

Not much progress to report, been super busy with work and it's cold now . Which kinda zaps my enthusiasm. I had to order another brake line kit from inline tube as apparently I have a drum brake kit on the car now? Brakes worked great but what ever.... so I have the new kit , still had to modify a couple lines. Latest piece of the puzzle is new Speedhut gauges. Just signed off on the art work just now. Should be real nice, kinda pumped to get them installed!
I was going for a stock AMX gauge look as much as possible . I think they came out pretty well!  Here are the artwork proofs and OEM AMX gauges... 

[IRON MAN]

The gauges look great. Like the direction of the needle sweeps on the four clustered gauges. Also prefer the elimination of the clock in the tach gauge. 

[YellowThumper]

Looks very clean with the proper period look

[Brads70]

Gauges arrived today from Speedhut . I'm liking them! 

[Chryco Psycho]

Nice , I like them !
