My lid alignment was a mess so I inspected the hinge mounts and found both had cracked welds. I re-welded them, put the lid back on, and the alignment was still a mess.
It's a GT style lid and I figured the force of the torsion bars was too much causing it to twist when fully shut, so I removed them and it fits perfectly. Only problem is, now it won't stay open on its own. Anyone have an ingenious solution to this? Simple metal prop attached to the lid? Small shock? Hydraulic air lift set up with nitrous oxide? Thanks John |

On the race car I removed the hinges and the latch entirely and have it held on with three hood pins. Makes it REAL easy to work on the car...you may not want to do this, but if you do...

Maybe bend up a copy of the torsion bar with thinner diameter rod?

I found using just one of the torsion springs was sufficient. The GT lid is also pretty flimsy so it is easy to twist the lid itself to make it line up. Mine was easy peasy. |

My lid is 'GT-lite' though - I bought the frame trimmed back to almost nothing and finished it myself by just wrapping it in expanded aluminum. It looks good but has zero structural rigidity. |

Not quite right for me, but it looks great. |

Someone had already done this to mine before I got it and I think it is kind of trick. GT style lid. Single shock strut. No torsion bars!

Good info,would one torsion bar be enough for a standard six conversion lid ? i.e. less rain tray etc. The gas strut is a solution but it does intrude into the engine space somewhat and its about finding the right one...too much tension and the lid twists as mentioned. |

But there are a bunch of ways/places I bet would work. Attached image(s)

That might be a problem... (IMG:style_emoticons/default/blink.gif) Good info,would one torsion bar be enough for a standard six conversion lid ? i.e. less rain tray etc. Have seen it done but the lid only pops up a few inches. Still the same issue in that the lid will need some help to stay all the way open. |
