the previous owner tore down the 12A . have all the parts except most of the bolts. we have the engine bolts to hold it together but we are missing the bolts for the stationary gears and oil pan and most of the other bolts needed such as the bolts to mate the transmission to the engine, bolts for the alternator, beehive oil pump, bolts for the water pump housing. does anyone know what size all these are and can i just go to the hardware store and get them.?
For the stationary gears, get the factory one used from some one. The others are kind of hit and miss,
When putting the water pump housing back on, don't forget the two spacer washers. The go where the gasket doesn't cover so that its even and doesn't snap something.

concerning our build
so we are rebuilding our rx7, the motor and transmission are out. I want to check all the electrical. can i just connect a battery? will all the systems work other than the stuff that doesn't need the motor, such as interior like windows dash gauages, wipers ect is there an ECU for an 85 GS? aka computer? that controls these systems? i know there is a fuse box. does that get power from the battery?

The basic interior stuff will work like rado, lights, cig lighter, pwr windows, etc. The gauges like temp, oil, tach will not work because the sensors are on the engine. The fuel gauge will work. Some of the idiot lights will work but not all. The computer for the engine is in the passenger footwell under a plate. It's not like a modern day car computer.

Electrical
I hooked up battery to it when I got it home and there was no power to anything. I did this to see if I coukd roll the windows up or operate the headlight motors. The window motors work cause I took the door panel off and hooked directly to the window motors. Previous owner removed a wire harness but I think its goes to the running lights in the front clip

The windows should work as long as you have the center console window switches hooked up. That harness goes from the switch, under the driver's seat to a connector, then up the drivers side footwell. The passenger side splits off from there. You do need ignition switch power.
Since you pulled the starter as part of the engine/trans pull, make sure you have a good ground since the major ground goes to the starter.

12a engine harness
Ok o have the FSM and a haynes manual. The previous owner started a emissions delete and removed engine and trans. I will keep the emmissions delete and I'm going to simplify the nikki. I am looking for a simplfies engine wiring diagram. With all emmisions deleted the AC was also rwmoved by previous owner. Just trying to get things to work without the motor and trans in, like headlighrs wipers dashlights, windows, ect. Put a battery in and get nothing. Does ignition need power for lughts wipers and such? What does the ignition wire look lije from the drivers side harness? Have an 85 GS. I have no clue on what pluga go where except for the obvious two large orange plugs on the pass firewall.

So we have been researching our 84 GS...according to the VIN. Also according to the VIN the GS had manual windows, manual mirrors, drum brakes in the rear and an open diff. I have been checking out our project, so far I have discovered it has PW, PMirrors, 4 wheel disc brakes, LSD, and lug nits instead of bolts....what gives? Accorsing to the VIN it shoukdnt have any of those things...any ideas?

I also believe the seat fabric pattern will tell if it's a GSL or GS option but I forget the pattern. From what I'm finding, the S and GS has dots and the GSL and GSL-SE had lines in the fabric.
