Lowered Truck Uneven

[TA_C10]

1970 C10. Lowered with a kit from brothers trucks. 4.5 front, 5.5 rear. Front passenger side tire is rubbing while driving when suspension goes full travel. You can see it's not level staring at front end too.

Is it suspension or twisted frame? Looking for guidance on next steps now that I have taken some measurements.

Here are my measurements:

wheel well(P/S) = 26 1/2
wheel well(D/S) = 26 13/16
wheel wells(difference) = 5/16
floor to top control arm(P/S) = 10 3/4
floor to top control arm(D/S) = 10 9/16
floor to top control arm(difference) = 3/16
floor to lower control arm(P/S) = 4
floor to lower control arm(D/S) = 4 1/8
floor to lower control arm(difference) = 1/8
lower control arm to top of spring perch(P/S) = 4 1/2
lower control arm to top of spring perch(D/S) = 4 15/16
lower control arm to top of spring perch(difference) = 7/16
floor to bottom of frame, front of truck(P/S) = 8 5/16
floor to bottom of frame, front of truck(D/S) = 8 1/2
floor to bottom of frame(difference) = 3/16
