22zx Hatch Actuator screws backing out
 

Anyone with the 22zx had this problem?

I have a Lenco hatch actuator and the screws on the lower end in the bilge have backed out. There is no shot at tightening them up at this point.

Should I 5200 and re-drill? Or is it possible to thru bolt....I'm not even sure if there is access to do a through bolt, maybe under the back seat? I'm worried about hitting the gas tank also.

Any help greatly appreciated!
