Alignment

Any one experience this?

I set the alignment after replacing the small lug dia with large froma 75 A body. Not real accurate. Just to get it to an alignment shop.

Every time I take it around the block I get one or the other tire to go either Toe in or out by a lot. Tire starts to scream (skid) it's so far out.

Stock steering components

Any ideas?
