Narrowed 8 3/4 questions

Hello FABO.

I got the 67 barracuda to go around the block the other day and had some rubbing from the backing plates to drums. I just shimmed them out to be able to go around the block again to sort out the alignment I did.

I noticed last time I was messing around with assembly of the diff I put the adjuster on the drivers side. Pretty sure that is incorrect.

Also, I dont remember dealing with the famed 'button'.

So friday I am going to take it to the exhaust shop so he can finish it out from the mufflers and that will be the first time since Ive had the car out for more than around the block.

Im feeling like I should at least give the diff a dirty eyeball and maybe trim the backing plates (yes I know I probably have mismatched parts but the wheels stop when I press the brakes.....)

My big questions are.......

Doesn't a cone sure grip get a button and the clutch type does not? or do I have that backwards. Last time I was in there I could swear that I could not see through to the other side so what is a button going to do? Much less how does the adjuster push against the other axle for bearing preload if there is a obstruction. Again, I dont remember being able to see.

How do I tell the difference betwix a cone and a clutch? (apologies for not using search on this one....just a guy....killin birds)

How important is it to have the adjuster on the passenger side?

Ill start with disassembly. I do have a different chunk around here someplace....a 3:23 489 case I believe...

Oh yes....this chunk is a 741 case with a 3:91 and its been narrowed.

Thanks for the help, I don't wanna burn something up if I can help it.
