6=8 and bore over?

The drifting around on the highway sounds like the typical worn front suspension bushings, steering linkages, and maybe steering box.

Can you describe a bit better what is meant by 'crapping out' after 35 minutes?
Well when i take the risk and drive it to work its a 30 min drive. If i stop off anywhere or traffic slows me up it starts stalling out. And it doesnt seem to be an overheating issue. For instance i drove it home from work and then went through taco bell drive through and it started stalling and had to keep the rpms up. And then when it dies from that its hard to start back up. I did a light carb rebuilt kit on it last year but is still having the same issues as before. Thanks
