(Honestly I still believes it would have ruined the aesthetics of the car. The aerial is probably more than enough to protect our heads anyway. :D )

I think that all of the roll over hoops sold by SPC/Simon Carrier were installed in cars - and it is an involved process. So none are likely to come up for sale unless fitted to a car. I tried to put a group buy together a few years ago, but didn't get enough interest, so I replaced my Elan for one with hoops already fitted. I think that this is the only realistic way to do it.

I have seen LGM rollover bars sold on here over the years, but they are few and far between.

IF i remember correctly someone started to question the integrity of the hoop ,
and like all good things it came to an end .

there are some pictures around somewhere of the fixing points but in the end they got sold as cosmetic hoops not structural .

DavidJT silver elan ( again i think as this was a long while ago ) had a nice set with the rear fibreglass cover.

Perhaps they didn't know what Simon does for a living ... :lol: Whether the Roll Hoop will do any good depends on the type of accident you are anticipating having... and there has always been a debate about their effectiveness.

In the early 70's Deny Hulme used to write a column in Autosport and it was interesting to read about the GP driver's attitudes to roll hoops and harnesses. Rindt didn't trust the effectiveness of the Brabham roll hoop so never fastened the crutch straps so he could slide down into the monocoque - his undoing in the Lotus 72 some years later. Dan Gurney was so tall his head was way above the roll hoop and he was too big to slide down ...Image

Hulme had a high speed crash in America, think it was practice for Indy, and he wrote he 'did a Rindt Tortoise' - unclipped and got his 'head inside the shell'. In that era getting out quick was important as fire often followed a crash.

Some of the roll hoops were not very significant either... integrity of this???

Image

By comparison the SPC design is massive. Thread here shows them in detail ...Kuching Roll Hoop

Collected a few pictures of other designs as I've been wondering about constructing something myself... some don't look worth the weight penalty, and some are downright ugly but ... 'every little helps' and there is plenty of evidence that the screen frame doesn't do much in an inversion. Even a bent roll hoop might prop the car up enough to get a door open. I've also seen photos of full harnesses fitted to cars without roll hoops which seems a bad idea to me - how do you do 'the tortoise'? :lol:

Another thought that has been crossing my mind is to replace the seats with a design that incorporates a roll hoop into a reinforced seat frame, and a full harness to keep you in the protected area ... alternatively an ejector seat .. :lol:

Leave me alone, I think I know what I'm doing.

If you are upside down then you need an ejector car!

Personally I like it and feel a lot safer with it than without. It's bound to offer a bit more than the windscreen on its own. Mind you, if the window collapses first then it's probably curtains anyway :(

I just hope I never have to try it out in earnest :?
