Ok, since I said I would do it, here it is.
First you need to have the items you need for the installation
Depending on your setup, you will need either two eyelet bolts, and two L brackets- If you have a 4 PT harness, with all 4 parts having the c clips on them
Those things^
Or simply two eyebolts- If your rear straps have the holes to be bolted in on them(not very commong, most have the clips like the above on all 4 parts)
eyebolts^
Ok….now the fun part
This is 240/silvia specific only.
Find some eyebolts that thread into the rear mounting bolts for the seat. There is one that his horizontal on the console side, and one that is vertical on the driver side. Replace the bolt with the Eyebolt for your harness. Make sure its tight please.
Go ahead and Clip in the lap belts there .
For your shoulder straps-
put them through your seat/in the middle of your headrest/racing seat holes. whatever it is that you are putting it in, make sure when you put it through, you cross the harness straps. This is for safety reasons, i really dont feel like explaining, becuase this is an install, not philosophy.
Once they are crossed like this
bolt them down to the seatbelt mounting points behind your seat using either an eyelet bolt, or simply bolting them down (depending on style)
Now just so you know the reasoning behind the mounting points told here
those are the acceptable mounting angles for most competitive organizations. Follow it, its there for a reason
Make sure everything is tight, and if you have any questions let me know.
I dont have any pictures of my actual car, Mainly because i dont use a harness on the street. When i go to the track, i switch my belt out for a harness, and remove it when i get home. I personally use a 5Pt RCI harness.
if you want to know how to mount hte 5th crotch belt email me and ill let you know.
If you have any questions, let me know. ill be glad to help.
