How can I remove the 4 bolts on the drive plate attaching the torque converter?

Ford Laser 2001 automatic 1.6L
There's no window to access the bolts which are attaching the drive plate with torque converter like in camry.

Added (1). Thanks for your answer. My next problem is locking the flex plate. Can I use a flat screw driver to lock the drive plate?

Remove the starer motor and access them there. You a large screw driver to turn the flex plate to get to each bolt. Make sure to push the converter towards the tranny after removing all the bolts so that you don't lose a lot of ATF.
