Distributor Question need help fast

[dakiddfb]

Hi guys i need your really badly.
I think someone sold me the wrong distributor.
Can someone take a look and see if this distributor will
fit a 95 b18b1 LS obd-1 engine?
if this is not the right one can somebody post a pic
or tell me how can i tell if the distributor is the right one.
I have a guy that wants to sell me one but i was told that 1 plug
distributors are obd-2?

can anyone help me quick

The housing part number on the casting (on one of the 3 legs, think should be on the leg furthest away in the pic) should be TD46U or TD55U for the '95 LS.
