parallel window regulator help

[grantsmells]

my '82 cab (with doors from who knows when) has parallel style window regulators, the motor was dead and window stuck up when i removed the motor from the regulator, so had to reach my hand up inside the door and VERY slowly remove the 3 bolts.
i managed to manually get the window halfway down, but still cant get easy access to bolt the motor back to the regulator, is there a trick to this? or do i just have to sick my hand up inside the door again and do up each bolt 1/6th of a turn at a time

the only info i can find is on the spider type 6 bolt regulators.
