Is this 4-pin or 7-pin Ignition Control Module?

Itīs ī84 Z-28 with auto trans and LG4 engine. I want to replace the coil, module, rotor and cap. I think they are original 21-year old parts.
Looking at the parts catalog there seems to be 4-pin and 7-pin modules so i went to see wich it had. But I didnīt get the rotor off. Are the 2 bolts on side holding it together?
Well anyway.. didnīt have right size sockets to remove them and didnīt want to break it either.

Can anyone tell from this picture wich is it?. On top it has the numbers "908 4002"
Thanks

Is that a vacuum advance can I see on there? If so, then it's a 4 pin module.

Hereīs pic from another angle.
I didnīt see any vacuum lines come to it
Maybe i should buy the right socket (1/4" is it?) and make another trip to see wich is it, but at the moment the car is stored quite far from where i live.

Ok, no vacuum advance on it, so no 4-pin module.

check to see what the price is for a new reman'd dist vs just buying the module. might be worth spending a few extra dollars and get a nice complete rebuilt unit.
