Kirbans 2 cents worth
Good job, I am sure you would not want to do several installs a day! I think the hardware we include have shorter bolts so they don't stick out as far.
We sell the front connecting brace if that is the one you are referring to that completes the triangle from the front pair of frame braces. Ties them altogether under the core support area. Probably offered by other companies as well. Its a design my son made several years ago. Early style was square welded piping newer version is vastly improved is a round bend tube.
I am sure other styles exist but more than likely the most popular ones seen today would be one of the 2 I have described above.
Another smaller similar improvement is check to see if you have the lower body bushings in the middle of your door area, just in front of your rear axle and the very last ones back by your rear bumper supports. If your car is not rusty in those areas a 15mm socket can remove those bolts real easy and you can drop in the body bushing to fill that gap.
Buick from what I understand wanted a different "ride" quality and that was the reason they never installed certian lower body bushings. However, in the real world of quick acceleration any slop in the suspension you want to eliminate..
If you get real ambitious you can install the GNX bushings which require a little more work since it sits on top of the frame rails over the axle assemblies. This requires backing out most of your body bushing bolts so you can separate the body from the frame enough to slip them in. Not an easy task to do on a garage floor, and one that should be done making sure you take proper precautions because if something was to go wrong you could lose a finger or two.

I have done hundreds of installs on front braces and lower body bushings on cars we have sold over the years, but only one rear seat brace kit!
