Title: fuselage disc brake ball joints/rotors
Post by: firedome on June 18, 2010, 10:09:28 AM
So my '71 F3ury III has the optional and kinda rare front disc set-up... I'm in need of upper and lower ball joints and maybe rotors - anybody have 69-71 C body with DISCS? I'm told that lower ball joints are hard to find... my NAPA doesn't have em either . Anyone got part numbers?

Talk to Jayme or Luke.  Tell them the master sent you (Steve Hobby or Polaraco)  They may cut you a break.
 
The brakes you have are the same as the 72 brakes.  They were used from 69 to 72 before they went to the one piece rotor.
 
By the way, they are the same ball joint.

Thanks - Llooked at 'em  - they have the same part # for '65 to 73 w drums, AND 69 to 73 with disc -  is that kosher ... ??  I thought disc and drums had different ball joints???

Sheeesh
 
What was the last thing I said? (http://www.moparfins.com/forum/smileys/smiley36.gif)
 
They're the same ball joint.  Buy the drum brake one and save the money

Only the BUDD disc brakes from '66-68 had different lower ball joints (and they are now about $400 each).  All the drum brake and the '69-73 discs use the same joint - about $100 each.

Are all aftermarket the same? Probably Chinee...?

How about rotors - are these the same ones Sjak Brak had so much trouble with for his Imp?

No you can still get them. . . Rock Auto has them for 150 a Piece.
 
I have an NOS set here, but Polaraco may need them some day

If you can get them for 150 each - GRAB 'EM!  I paid over $400 for the 2 disks I put on my car.

Yer screwed

Best thing you can do is take one to a independant parts store and match it up.  Or convert it to 73 Rotors. . .If you can find themPOLARACO2010-07-19 15:45:07

We need someone to come up with a conversion that will allow using the 74-78 front suspension pieces.  They, relatively speaking, are still readily available aftermarket for not too much money.  This would be good, because it would restimulate the interest in those years parts and the manufacturers will take notice.  Thus possibly continuing a good supply for many years to come.

Hey Stunley.  Speaking of disc brakes. . .
 
Do you know if the 74 and up Caliper brackets will fit on a 73 spindle and align properly?  Don't the bolt down instead of the pin through the back???
 
Need to know

Guess as long as the caliper bracket is essentially the same you could use it.  Again another thing I've thought about as well.  If they use the same rotor I can't see why there would be any difference in the caliper bracket.  The caliper didn't change much except to go from the pin type to the bolt down style.

Well from the blow up pics there Stan, I think maybe the lower control arms and the spindles and caliper bracket and caliper might work on a pre 74 C-body.  The upper control arms are a bit different, but I guess they could be made to work wit the addition of a bracket?

It would be great if someone had these parts, and a pre 74 C-body, and could do a little experimenting.

It is my understanding (perhaps in error) that from '73 - up all are interchangeable which is why I was suggested to get '73 and up.
 
I ended up with a '71 set and paid through the nose!

Hell I didn't know that Snotty. . .I had a good set of 71's here with rebuilt calipers and hoses no less.

This is why the 73 C-body set-up is the coveted one.  Runs the later 74 and up rotors, which were used on almost every mopar with disc brakes up into the late 80's, which means CHEAPER!!   But they also ran the earlier pin type calipers (69-73), not the bolt down style.  The bolt downs didn't appear until 74 in cars.
