I replaced my lower control arms, They tell me the car slightly dog tracks?? The distances between the rear fender wells are not even?? What would be the cause? everything seems to be tight. Would a adjustable set of lower control arms work?

I have more questions for you before i could begin to give you an answer. I assume you had an alignment done and were told about the dog track issue. before you try to adjust out your problem look at the alignment spec's. In the most basic form.
Thrust angle will = dog track
This the the angle the rear end is in relationship to the vehicle center line.
Set back is the relationship from one control arm to the other.
A set back on one control arm and a thrust angle in the rear could indicate a diamond in the frame.
Excessive thrust angle could be caused by a bent housing, brkt, ect.

More information from the alignment specs are needed.

Possible bent frame?

different distances between rear fenderwells (I assume you mean tire clearance) could also be caused (pretty common) by loose/worn/misadjusted body bushings... The bushings are rubber and could allow a misalignment, especially after 35+ years of service... Maybe even misaligned when new (production)...

Adjustible lower arms should not be needed. You need to find the cause instead of just using a crutch to make a quick-fix...

The thrust angle on my alignment indicated 0.85 degree.

The cars previous life at the drag strip have an effect ??

Thanks
