1969 Dart Street/Strip (Re)Build
For all the repair work made to your factory tower.....you are fortunate. I remember we discussed mods to that shock mount before you even ordered.......glad that was not needed.
I did a Hemi install where the right tower had been hammered for valve cover clearance. (The HDK does not require that modification). Regardless , a small section of the rear of the HDK upper shock mount had to be milled off to get a solid fit.
Of the cars I have personally installed HDKs in....over 25....I have never noticed even ONE that the sheet metal was pushed away significantly from the factory upper shock mount. One of the functions of the HDK upper shock mount is to strengthen /reinforce the factory shock mount. The sheet metal inner fender has NO structual support whatsoever.....it is just there.
It is hot roddin....Enjoy the ride.
