    I used summit brand connectors on my 79 ttop. They are basically the same as the competition engineering. Had to notch a couple holes on them like the instructions say but other than that fit nice on the floor. And it's not just ttops that have sag in them. I've seen plenty of non ttop cars with tiny cracks at the top rear of the window on the roof from twisting and not just on high HP cars.

    Why? Is it because the undercarriage is neglected?

    No I've seen it on mint condition cars. I think it's probably just the use of unibody compared to body on frame with the torque of V8s. New cars are just much more rigid and stiff just technology progressing.

    that does have alot todo with it,now days the manufacturers put more engineering in the structure than what they did years ago .thats why the newer Camaros are bad ass track cars out of the box compared to factory stock 2nd gen. which brings us to threads like this to upgrade and make better our 2nd gens that i personally think look better. just think if GM did a retro like they are doing with 1st gen???

    Thats the thing, most users here are track dudes and im not. So I wonder if its worth doing all this stuff but its still interesting.

    for a mildly driven street car you don't need to do anything outside of making sure your subframe mounts are in good order.

    Any sec gen car benefits from SFCs. The body does have a lot of movement and just jacking the car up will bind the doors. If SFC don’t fit, the body is sagging....I have had to “jack” and push SFCs in place to fit them.

    Exactly! Thank you! They are! My car had a sag before i got the mounts put in because the old mounts were completely crushed and uneven. Once i changed the six mounts, i felt taller in the car and i could almost touch the roof with my head. I knew then that the car had sagged but the bushings were never changed in 30+ years...
