Relocating the rear differential 1.25” towards the rear of the vehicle on a 72 Dart

-
It will work fine = We have it on both our 10 Sec. Street Valiants.
However, it is a bit noisy of adjusted properly.

Going to call Calvert Racing in the morning and check into a mono-leaf setup with caltracs.

Not too sure about how it will behave on the street.

It will be fine. The avatar has that setup with the split mono springs. Noisy? Mine make a noise on part throttle 2-3 shifts on the street but that's all I ever hear. Deep throttle, the engine is LOUD so you don't hear anything from the suspension!
 
All of ours make a loud clunking noise when shifting gears
especially 2 to 3.

We leave in a small town where everybody know us, so we
are only at full throttle at the Track.

We have Pro Trans reverse Valvebodies that shift hard, that
probably aggravates to clunking compared to a stock transmission.

@GTX JOHN are you running the sliders?

I talked to Calvert this AM and they felt I would be ok just using the rear shackles, I too am running a reverse manual 904. I am also under 500 hp. If needed I could add them later.
 
We do not run the sliders even on our 8 or 9 Second Mopars.

John Calvert is our friend and the sharpest suspension man I know.
The Calvert Family (John/Brother/Sons) are all very formidable racers
that we hate to see in the other lane!


Do be sure that the shackles are angled a bit backwards so they
do not flip forward.
 
Thanks JohnI might give you a shout if I get into something I am not sure of.
I you can swing a deal on the pricing I will order everything through Calvert.

Otherwise I will probably be ordering through summit, so if you have any of those codes that would be awesome!
 
PM me and I will send you a few.

If I post them here someone may use them before
you do and they are one use only (Entire order but one time).

Look me up if you ever get out my way again = Enjoyed meet you
last time.

I have a 72 dart setup identical to what you are talking about, dana 60 moved back 1.25, caltrac setup with sliders etc. I drive it a ton on the street and a fair amount on the freeway and I can say I think it drives better than it did with all the stock stuff. Is your car painted green go?, that's what color mine is.
 
The color is by Tamco it is called Toxicity has a gold pearl mixed in. Real close to Limelight.

Did the 1.25” relocation affect your shocks and differential potentially hitting the fuel tank?

I'm glad to hear this @GTX JOHN ! I've always thought the 2-3 shift CalTrac noise was just my car. I also have a RMVB but mine is a name you'll probably recall from the past: Griner. It's in my Cope 727 trans. Low band apply, etc, etc. It's a keeper for sure!!
