Trying to make sure I have all the necessary hardware before I start. What size eye bolts do I need, any long ones or just standard length? This is for a 6 point, driver only

 

They should all be 7/16" size, it's a standard. 22-25mm long is fine, no need for long ones. You'll probably want just two regular eyebolts, for the anti-subs (use backing plates). For the lap belts, I used these: https://www.hmsmotorsport.com/produc...-brackets#1584 so that they didn't foul the seat. On the outside belt, I just added one to the stock OEM belt washer/attachment stack and removed a shim/washer or two from that stack so that I still have similar threads available on the bolt. On the inside, I drilled the transmission tunnel and added a backing plate.

 

There are fuel lines passing under the car where the sub belts go, right? I'm also in the position of being about to install my harnesses as well.

 

The answer to the question I asked is.... the left sub bolt/backing plate is fine, the right sub bolt sits inside of the plastic carrier, but if planned out works fine.

 

Yes, you will have to move the Fuel line cover and end up drilling between two lines.
