to all that have installed a full cage with A pillar front bars how did you attach them to the frame?
i have a rear hoop and down bars installed already and i am getting ready to install the a pillar bars but im not overly sure how to attach them to the frame. i have a few ideas but i thought i would ask the experts here to see some other ideas.

thank you
i dont have a full cage, but i do have a 6 point and the non removable diagonal sidebar mounts to a ledge coming off the frame .
i would imagine you could build a ledge off the frame like this, more forward (where the speakers are) and then put the up bar off of it. (After removing or cutting up the dash)
might be tight confines for your leg vs. the clutch pedal but who knows maybe it will work fine

This is an old photo of my swing out door bar good for 11.50 per division two tech. DRM 4-point roll bar with side bar.
Removed right front speaker had pivot point welded to frame with thru bolt so bar swings out when yellow pin pulled out (a lot easier for me to get out).

would yours work with a clutch pedal?
or do you think the cage would intrude upon it
I should have added this is a manual car, pretty much drag race only at this point so not overly concerned about long drive comfort but i do not want it to interfere with the clutch.
im pretty sure the down par will be more up my they dash, with the frame of these cars basic sitting on top of the body and the door shutting on top of that cage mounting is a real challenge. i do have the advantage of not dealing with interior, speakers, etc.
I wasn't exactly thrilled with this. I had a halo and down bars added to a 6 point roll bar.The chassis guy got it backwards even though I had written it out on paper (should have written on the floor and rockers instead) and I told him at least a dozen times that the rockers are steel and the floors ahead of the seats are composite. At least the upper part of the step plate that the down bar is welded to is on the frame, albeit being separated from steel to steel by composite. His solution was to weld the tube to rocker brace in. I'm too old to be climbing over the door bar so it was left as a swing-out.

to the rear of your downbar mount point
there is an additional brace bolted in the photo (black in color)
what is this brace ? What does it do and where does it go to

that was one of my thoughts as well was to support it up the side of the rocker brace because i was was little worried about getting a weld 360 around the base of the bar, with limited space in these cars you defiantly have to get creative lol. thank you
so after i got the cage kit i am more confused, it seems the top hoop is on the narrow side and im trying to sort out how it all goes together. would you all happen to have a few picture of the top hoop and a bars i could use for reference? i am going to call the company as well but i figured some real world examples would be nice as well.
