lets see some rollcages,

A full "cage" is a minimum of 10 points, with a halo and braces from the front of the halo to the front floor. That is only required under 10.00 seconds or over 135MPH. I suspect what you are after is a roll "bar" - a minimum of 5 points, uncluding the hoop, two braces to the rear and one diagonal brace past the drivers arm to the front floor..... correct?

That's a custom built, all chrome moly setup, to my specifications. The hoop and front braces go through the floor to the subframes, and there are custom chrome moly subframe connectors included. Shop did the entire job, from stipping the interior to returning the car in spotless condition, painted to match the interior, and a Simpson camlock 5-pt harness, and brace for the back of the stock seat. Designed for conversion to a full cage. About $1,500.

Here is a road race cage we did in a 3rd gen ...

We did everything in-house. Surprisingly enough, the inside demensions were very, very close between this 84 and the patterns we have for a 4th gen.

I wouldn't consider a bolt-in. The floor pan is just too thin to support the weight and impact if the cage is ever put into service.
Nor would I consider ERW tubing. ERW tubing will split at the seam. Insist on DOM tubing, 1 3/4", .120 wall for a heavy 4th gen.
A cage is one of those things that you really need to work and work well when called upon to do it's job.
I've witnessed roll-overs and wall contacts that have ripped the floor pan of a bolt in cage. Conversely, I saw a Porsche 911 take an 80mph shot in the A-Pillar from another 911. The energy was sent upwards and away from the driver and his legs. The cars were toast, but the drivers walked away.
Welding proper floor plates to a structural part of the car and then welding the cage to the floor plates is a must for it to work properly.
