72 Dart

History: 72 Dart Swinger, 318, 907, 8 1/4. 75 front discs for the bolt pattern.

Originally this was a power steering car. I replaced with a manual steering box for clearance reasons.

I'm currently running 225/50 15 tires on 15X8.5 American racing 200S wheels.

Problem: I set the front end up so the tires are visually straight, with zero camber (visually) so I can drive this car to the front end place.
I drive it around the block and either I have extreme toe in or toe out, and the suspension has gained about 1-2" in heighth. The tires squell quite a bit about half way around the block.
So I reset and do it again. Same result.

Any ideas????

Thanks
