Need Alignment specs

[Truckhead]

If i can, i need to get the frontend alignment specs for a 1970 chevy C10 2wd w/350,th350. I've got an ECE 4/6 drop and disc conversion. I think that alot of alignment machines don't go back to a 1970 model year and i assume the techs are just using the earliest 2wd chevy listing they have. I was watching the tech scroll through his listings and i didn't see my year, so i figured he might have used the 73-87 year specs.
My trucks aligned but it just don't feel "settled". I've got the alignment specs printout and everything looks right. While the truck tracks straight the steering feels kinda quircky, can't explain, just it doesn't have the right feel.My truck felt better when i eyeballed the settings before the alignment.

Thanks.
