full cage

[kitcarkid]

hello i need some help, i am thinking of starting a haynes roadster

just having a few thoughts,
i want a full roll cage that has a windscreen built inand will be completly water tight when a hood and sidescreens are attached

any one know where i can get this made, or possible suggestions??

the type of full cage i want is like the mk indy (bars above head are centred) for easier access, my car will only be used on road (if that helps when planning the cage)
