Not familiar with this kit, but starting in 1970 B bodies had the factory calipers mounted towards the front. Is it possible your hoses are the correct length for this mounting?
At least check the instructions again.
Ok, took my own advice and looked at the instructions, they do say to mount them to the rear. And this probably the only way it will work on a '62-'69 with a factory sway bar, But on a '70 or later I'd swap the knuckles and mimic the factory routing, as the hard lines on your chassis are set up for this. Just my .02!
