8 3/4 is this correct

[R4Sedan]

I'm pretty sure this is correct length. For stock A-body.

Most people measure to the spring perches, I think.

 

[toolmanmike]

Yep! If this chart is right.

4-speed, 904 or 727?

That has nothing to do with differential housing length?

Yeah Barry your right. That has nothing.

I know it's suppose to be 52 5/8" it seems to be a tiny bit over. ????

 

[Alaskan_TA]

It appears that he edited his post, so maybe he caught it?

Friday afternoon after beer break.

What is center to center on the perches?

That's called "manufacturing tolerances", +/- some "X" amount

If you're going to run a spool with the green bearings that little bit won't make any difference at all except for putting your wheels a fraction of an inch further out.
What comes into play is 1 axle tube longer than the other?

There not there I would have to weld some new ones on.

 

[MoparMike1974]

Yeah, this is normal. I have a three originals and all are slightly different by a 1/16"

I'm going to run a clutch type sure grip. 741 case.

It's a little less than 52 7/8"

 

[Jadaharabi]

What axles and what wheel bearing?

 

[R4Sedan]

What axles and what wheel bearing?

I'm gonna order them from Dr. Diff

 

[Jadaharabi]

Being a tad over using green bearings won't hurt.
But if going with OEM bearings then things need to be righter because you are going to be adjusting the end play by thousands of an inch. So if one axle tubes is an 1/4 off of the other things are not going to work so good.
Dr. Diff is the man to work with. He will do you right.

 

[451Cuda]

Width 52 5/8" , spring perches c-c 43"

Yes I know, Thanks

Yes it had Oem bearings on it. I will be getting axles and green bearings from Cass. Sounds like it's Factory typical 1/8" + or - tolorences then.

Yeah, that looks wrong. You should let me have it, I can come pick it up tomorrow!

 

[R4Sedan]

HAHA

I’ve got some new perches if you end up needing them. PM me if interested.

 

[72Dart6pack]

Maybe the housing it correct. But the tape measure is off. You put too much trust in a unknown measuring device. Just a thought?

yeah, it's a "short-bus" tape, so it just might be off.
