Right now the stairs are working like a charm and I'll get that 3rd bolt in town tomorrow. Thanks to OP and all for posting your findings.
A Cardone p/n 42-309, 1990 Ford Taurus left front widow lift motor...($53.99 at Advance Auto Parts in 2010), fit my 1996 Kwikee 2 step with no modifications
to the step or to the motor.
(BTW an ACI p/n 83694 is also an exact replacement).
