Cheaper options do exist. Scott Drake has a couple of pair, Scott Drake C7ZZ-5258-C & C7ZZ-5258-GT2. Another option is United Pacific, FM003. All "correct" are going to fit a 2 1/4" pipe.

All 69 Mach1 received the stainless rolled tips. The "exact" repo are quite expensive. But there are several lower cost alternatives.: https://www.npdlink.com/product/tail-pipe-extensions/214326/200414?year=1969

I would start with measuring between the frame rails near the radiator support and where the frame rails enter the rail extensions. Compare to ensure they are the same. If the are not the same one or both rails are not strait. Next I would find fixed points on the rails to make cross measurements to decide what if a thing has moved. Assuming all of the above checks out I would note all of the dimentions as listed in the attached thread. Note: There will be variances between cars. If your afraid the rails are going to move, they should not if there is no stress in the rails, one may brace them before cutting anything out.

Spray done into the cap and brush it on. or just don’t use it in those areas. Weld thru primers makes for lots of splatter as you burn through it as well as it makes porous welds. When I do use it is I scrape it or wire brush it from the direct weld area.

If the desktop size is the same & only what your viewing in the browser then likely some browser settings have changed. Chrome has 3 dots in the upper right, click the 3 dots & adjust the "zoom" setting. Firefox is similar except it has 3 bars in the upper right, click the bars & adjust the "zoom" setting. OR if your mouse has a scroll wheel, hold down the "ctrl" key & spin scroll wheel.
