I believe if you order a 8- or 10-point rollcage for a uni-body vehicle, it is supplied with 6X6 steel plates to facilitate it's installation. Most of the "popular" vehicles have sub-frame connectors available, but I personally don't believe that the connectors are an adequate substitute/replacement for a full frame when installing a roll cage. Just one person's opinion!

Frame connectors are a necessity to keep the front spring boxes from pushing out .
With modern torque converters , tons of gear ,radials and Caltracks, ect. , There is way too much force concentrated in that area to forgo the connectors. Also be sure to tie the main hoop braces into the connectors. If it's a Mopar or Ford, I also run braces from the front bars to the firewall area at the top of the fender trough, You cant go thru the firewall in Stock , but you can brace it inside.

John Calvert ran his original 68 1/2 CJ Mustang (4-speed) for years with a bolt-in roll cage and no subframe connectors. I believe tech finally said no and he took care of it with a welded cage. Not sure if he has sub-frame connectors now. So can it be done? Yes. But is it wise? Not really.
One costly mistake I made was not placing rocker bars (at least on the drivers side) when I went from a roll bar to roll cage and switched to SS/H at the same time. Although I had sub-frame connectors from day one, even with a CM roll bar, the extra 100 HP, 6800-7200 RPM stick launches and Cal-Track system reeked havoc on the drivers side torque box causing an eventually dangerous ride. And it's been parked since. I believe rocker bars would have eliminated the problem. And it wasn't for lack of funds, that extra part may have been $20-$50. I just didn't think it through.
