Bolt on full cage

I have a stalker with just the roll hoop in back. What does it take to bolt on the additional parts (front roll hoop) to make a full cage. Just the roll hoop, not the additional side surround bars. Anyone have some pics and recommendations/cautions/suggestions?

To add to this wish, I like the functionality/safety of a cage on track but don't like the look and would like to take it off cruising around town or going to a weekend car show. Can that be done easily?

I'm talking to a race car cage fab shop and he's estimating about $1200- 1500 for a nice tidy bolt on removable job that should be structurally more sound than what I am seeing in most pictures. (Looks to me like the front hoop misses the ideal support by 4 inches.)

He asked if the square stock in the lower and upper rails of the frame was .095 thick. anyone know or should I just EM Scott?

Ted, did you ever figure this out? I'm curious about the thickness of the stock used on the frame.

Dave, Scott told me "The upper and lower 1 1/4" tubes should are 14g, and the roll bars are .120."   I don't know what the thickness is for the round stock in the frame.  Scott was quick to respond so give him a shout if you need that dimension.

Got my bolt on front hoop/full cage done by a 30 year experienced race car fabricator with the SCCA regs manual sitting on his work bench. $1400. Not the full meal deal of a Caterham race cage with side bars, but adequate for me if I want to do some low key SCCA racing.
