6.1 Hemi 69 Barracuda Fastback Father Son Project
It is just standard '73-'76 A-body Upper Ball Joint from Moog.
I don't know who made the one on the left, but with the dome it would not clear a 17" wheel.
You may already have the correct type on the right.
Once you are "over" the ball joint your limit becomes the outer tie rod (OTR). So perfect offset on 17" is what leaves you a little clearance on the OTR.
With my '73'-76 spindle and Cordoba rotors that turned out to be 17x8 with 5.5" backspace, or a 1" offset wheel whichever way you want to think of it.
This is with 17x8 and 245/45-17 tire. These wheels and tires are on Josh Walton's car now. Prior owner of Josh's car is a friend.
When his car was in the body shop we used my car to fit test the wheels and tires since we had same suspension and brakes.
To go beyond a 245 under the car you would need to go to an 18". 18" clears the OTR. Then your limit is turn in to rubbing the frame.
You are limited to 25.5" tall tire without trimming the front edge of the wheel opening.
To go 25.5" or shorter on an 18" does not leave much sidewall. The 245/45-17 is a good look and has some sidewall.
My car is now fitted with an 18x9 and a 255/40-18. I have tested and can fit a 285/35-18. I like the 26" tall tires on a 18" wheel.
