71 Rear End into a 73 questions

[Fitz73Chrgr]

I'm putting a 71 8-3/4 under my 73.  Does anyone have pictures of their 71 8-3/4 mounted under their car that shows the spring/shock mounting brackets in detail as well as pictures of the brake lines mounted? 

Also, can the 73 springs be used with the 71 rear end?  It seems that the mounting bolt in the springs is too large to fit through the mounting hole in the 71 rear end.  Can this mounting bolt just be replaced with a smaller one?

Thanks gentlemen.

Look at any b-body charger before 72..mounting bracket is all the same.

As for the springs, if you can change the center bolt you can use the springs...the bolt is larger due to the fact the 73-4 springs were mounted to isolator pads for a smoother ride.

Is the 72 different than the 71?  I'm missing the mounting brackets is why I ask.  I found a guy parting out a "71", but I think it might be a 72, hard to tell from pictures.

All the same.

axles are the same except pedestals for the isolation clamp/pads assembly between 7172 and 73/74

Springs:
71/72 are the same.

73/74 are the same. BUT:
front spring isolation became thicker on 74s making a smaller center bushing. That made a smaller thickness bolt, and of course front hanger with smaller holes for it.

71/72 5/16 guide stud

73/74 3/8 guide stud with an added sleeve to reach the isolation pads location

Now, will the mounting brackets from a 71/72 8-1/4 work for an 8-3/4?

the diff is the same no matter the axle. Brackets are set by the year not for the axle.

I don't think there is a diff of diameter of axle tube to fit the bracket... or it does ? I alwayas that I have seen selling brackets ( do you mean pedestals/perches ? ) never have seen saying for one or another axle
