I'm getting the 5-point seat belt harness from the Lemons store and need to know now many eye bolts to get. I'm guessing that I only need 3 correct? 1 for each side and 1 for the middle belt. The top two belts attach to the roll cage right?
You'll need two mounting locations for the shoulder belts and one for the submarine belt. Make sure to mount your shoulder belt as close to horizontal as possible directly to the rollcage with large, grade 8 hardware. The submarine belt should be vertical and mounted as securely as the shoulder belts.
Make sure to check if you need backing plates for any bolts that go through the floorpan too.

I think you mean lap belts instead of shoulder belts. The shoulder belts are normally attached to teh cage.

That makes sense. So it looks like I only need to get 3 eye hooks/washer setups, and 3 harness snap plates.

That would be true if you looped the belts around the cage, but some people anchor the belts to the cage. So actually, you would need 5 anchors for that configuration, or three if you loop the belts.

Be careful here. Mike is right that they should be as close to horizontal as possible, but they can go as high as 5 degrees (toward vertical) max. They CANNOT be lower than your shoulders! If they are too low it can cause compression of the spine in a roll-over situation.
The reason I say be careful is that the horizontal member most use for their shoulder belts on the main hoop can be too low depending on the height of your drivers. Ours was two low in the cage we bought for our E30 last year, so we added another bar on top of it to make sure the angle of the shoulder belts was correct.
Another safety related item that is overlooked is correct placement of the fire extinguisher. Mount it somewhere you can EASILY reach it in case you need to use it. Behind you on the diagonal of the main hoop is NOT a good place. IMO, the optimal place is right beside you on the tranny tunnel. You can reach it easily without even un-doing your harness.
Install the harness with Zip ties... don't worry they will hold!
