i'm doing a clutch and flywheel job, or trying to rather, all i have left to disconnect is the bellhousing from the block, i've got the lower 2 bolts off of the right side as well as the lower 2 off on the left side, but i can't get the top 2 bolts off.

my dad who used to work in a shop said that they always used to use extensions and swivels to get them off, i tried that with both a ratchet as well as a impact, but i cant get enough torque with the ratchet or breaker bar, and the impact isn't working either, i've tried from the top with a wrench and a bar and i can't get that either. this is my daily driver, i'm borrowing a car from a friend for the time being but i need this back on the road asap!!!!

anybody got any tips or tricks? I know you do, YOU GUYS KNOW EVERYTHING!!!!!

thanks in advance guys
