So I think the car had abs, got into an accident and to cheaply fix it, replaced the brakes with non-abs brakes. My problem now is I don't know which MC to buy. I think the non-abs master cylinder. Any opinions? Thanks

Your car should have had ABS when built.  However, a lot of these old 
ABS systems stop working properly and are hard to fix.  I "killed" mine 
by removing the relay, the idiot light, and the dash switch (so no one 
would ever get confused into thinking the car has it).  Another 
"solution" would be, I suppose, to bypass the ABS unit itself.

The ABS unit is the big black rectangular thingie between the master 
cylinder and the coolant reservoir, with a fat wire bundle coming out 
the front.
