help with hatch latch and alignment

the hatch striker bushing broke a while back, and i put a door one on there. seemed to work the same, it was a little too short and slid up and down but it worked. so the other day the one i had on there broke, so i got dorman part number 38424

from advance to hold me over, however now i have to kinda slam the back hatch to get it to shut. is my only option to get the 50 dollar striker and bushing from ford if i want a permanent fix? latemodel sells replacement striker bushings for the doors, but not the back hatch, and i put a door one on it and it broke. the door ones didn't hold up so well either, i ended up putting the oem ones back on.

also, i think some how my hatch has gotten shoved back. the gap between the roof and hatch looks fine, equal, about the same it always did, however if you look at it by each tail light, it looks like its shoved over to the driver side some, and the gap between the driver side tail light and bottom of the hatch is bigger than the passenger side. you can also see a faint square where the latch mechanism is hitting the weather stripping. the only way to align this is to just loosen it and put it where i want it? the car did rear end someone a while back, could that very well be a problem with the chassis being out of alignment?

this is the passenger side gap



driver side



and the gap at the top
