Looking from butt to muzzle it needs to go left.
As is it should shoot left below your 35 yard? if its the A frame. May be the mounts not centred over the dovetail or similar.
if i zero my aa s410 (.177) at 35 yards and shoot at 45 yards, the pellet strikes below and to the right of the centre of the target (when aimed at the centre). which way do i need to alter the barrel? left or right?
cheers, Andy

Are you sure that the barrel's centred in the cylinder clamp? You could slacken off the clamp's grub screws and let the barrel find its unstressed position - then retighten and check your zero. Regards.
Are you holding the gun dead level (ie not on the cant) or is the horizontal reticle set horizontal - does the vertical reticle extend through the centre of the barrel etc?
Simplest fix for crossover is to slightly cross your eyes when taking the shot, as if you're trying to look at one of those 'magic eye' pictures.
Works every time!
BSquare adjustable mounts will get rid of cross-over, optically centre your scope first. They are a bit more expensive than ordinary mounts.

The ox is slow, but the earth is patient.
You could have the clamps on the mounts the wrong way round, try flipping them over.
Thinking about it you could have one one way round and the other the other...that would do it.
