Center the wheel in wheel well.

Is there anyway to center the wheel in a wheel well?  I just put 235x70 r15 wheels on the front of my 70 and the front right hits the fender when turning right.  Measured and there is 3/4" clearance on the front and 3.5" other side when the wheels are straight.  Driver clears no problem and the wheel is centered in arch.  Panel gaps look similar on both sides of the vehicle.

A close inspections of all components and their mounting locations is in order. Additionally, alignment measurements should be checked to see where they fall to ensure there is no wide varition from right to left. Backspace of the wheels on both sides should also be checked to ensure they match.

I was thinking that too-the wheels are probably mismatched...

Have you ever noticed there is actually a diff ?

On my car ( and many 71/74 Chargers I have checked ) the passenger side wheel is around an inch DEEPER into the wheel well ( fender ) than driver side. My car never has got any front damage.

I think it noticed it before but never thought about it.  The wheel on the right side is actually closer to the front of the vehicle and the tire hits the bottom front edge of the fender when turning hard right about halfway through. So clears at the stop and straight  travel. I will check measurements on each side but was not sure you could adjust that.  Caster maybe?

and I think on my car the frame rails are not simetric... engine is actually off to the passenger side too

The actual frame rails should be symmetrical. The K frame engine mounts are offset to allow room for the steering box.

Yes, caster does move the wheel slightly, but unless you have 10+, it shouldn't be contacting a fender.

235/70 is a really tall tire at 27". Obviously this is a candidate for contact somewhere.

How do the two sides compare for clearances when put through the same motions? They should have some cross caster dialed into them for alignment, but should not be radically different on placement. Certainly after 40+ years, it is possible they have been reassembled with mis-matched or damaged components that create significant differences.

yes now I think on, since bumper brackets are symmetric, then frame rails must be too, but is a fact my passenger side wheel is around an inch deeper into the wheel well

Yea it is pretty tall.  Next time I will go a little shorter :)  I can reach the drain plug again though without the car jacked up though.  The left side is fine it gets close on the front end but clears okay.  With the wheels straight that side was 1" away from the front edge of the body panel.  I played with the caster on the right side and got a 1 1/4" last night now on the right.  Will check tonight how much it clears through travel.  Inside the well itself both sides clear everything just fine.

Should clarify driver side of vehicle when the wheels are straight has 1" clearance between tire and bottom front corner of inner fender.  Backside clearance of the driver side is over 2.5".

Passenger side when it was contacting had 3/4 of inch to the front corner of inner fender.

So you have a combo of 1/2.5 on the driver side and .75/3 on the passenger side. In all honesty, that falls within the tolerance guidelines of factory assembly, which allowed up to .25" of variation in chassis and panel assembly.

Addressing changes that small will be tough. If the K frame is off .075, the control arm is off .075, the strut is off .075 and fender is off .075, you now have a stack up tolerances that create an interference point.

Best bet is to see if the additional caster will create the sweet spot of clearance.

Ok.  I will try that.  I was more surprised of the front to back than driver side to passenger side.  Thanks for being a sounding board.
