Anybody try this without moving spring perches on the axle? The perch width is only 1/2" wider per side, thought some Mopar offset rear hangers might do the trick? I have a 67 B body Dana that I invested a lot in and need a Dana for my Dart project. I can't recover my cost so why not use it with out cutting an original. The car will be a lowered 68 Hemi street monster with wheel wells trimmed like a stock car.

It isn't hard to move the perches. I usually cut one off with a 4" grinder while leaving the other in place. Set the axle on 2 4"x8" blocks, one under each spring perch. After removing one, slide it toward the 3rd member by 1/2". Tack weld. Remove other perch, slide to where they measure 43" center to center or from the outside edge to the inside edge, tack weld...Then fully weld all 4 sides. By doing it this way, the pinion angle is undisturbed.

I understand as we do axle work like that in our shop, I just don't want to cut up the original Dana. Thanks

If it's a real B body Dana you might be better off to sell it and make a Dana for your Dart from a pickup Dana.

You sure you want to move the springs out...on a dart?

The springs will give enough to get the axle on the center bolts, but do you really want the springs to be bowed in the center on a Hemi car?

Another thought is if you are lowering the car, it is possible to add a 1" or a 1 1/2" lowering block between the axle and the spring. If you make your own blocks, you can off set the holes for the center pins. That would allow the springs to remain straight, and would keep the Dana original. The U bolts and the shock plates would accommodate the minor offset on each side without issues. Gene

I never had to move the spring perches to use a 66-67 B-Body rear in an A-Body, no need to. I currently have a 68 Dart GTS witha B-Body 8-3/4 in it, pretty much a bolt in.

Thanks for input.
I turned the front hanger up side down and that will move the eye bolt up 2", lowering the car approx 1 1/4" . I'll have to figure out the best way to fit the bolt pattern on the hanger going into the chassis, hopefully there is enough room on the body.
I'm probably starting off with the wrong springs- car came with 002 & 003s, anyone ever try having some of the arc taken out of the leafs?

Using leaf spring bearing sliders on the rear will also help lower it a little...
I have 002 and 003 SS springs on both the Dart and the Duster...Both with sliders and both also have the front spring hangers installed upside down with the holes at the top...
No lowering blocks were needed...
I never checked the perch vs. the pinion angle between a B body and an A body...evidently it works left alone...
Both of my cars had the perches removed after the above modifications and then the pinion angle set...Removed the rear a final time and welded everything up...

Thank you for not doing this. I walked the face of the earth to find a '66-'67 Dana for my '67 GTX. We don't need something this rare cut up.

Thanks, I bought it to cut and put in the Hemi Dart, its too nice to chop so I rebuilt it. Unfortunately I can’t recover the 3000 I have into it so it’s going in the Dart without cutting. Someday maybe a guy will put in the correct car. Power tour here we come!
