Top strut bolt help

[Droveby]

2024 Mustang. Yesterday I installed new springs and camber plates on my Mustang, it was my first time doing it and was a fairly easy process. My question is in relation to tightening the top strut bolt on the strut assembly. While out of the car I hit it with an impact quick just to get it going and didn’t crank down on it hard at all. When I got it in the car and spindle connected it hit with the impact again until tight and counted the threads in comparison to the stock one and the new spring was showing 5 exposed threads to the 3 of the stock side. I did the same for the other side which also is showing an exact same 5 threads. Online I found the torque spec should be 76ftlbs and got my torque wrench out to torque them to spec. I started low at 25ftlbs and slowly worked up and got to around 50ftlbs. However, when doing this they seemed to not tighten and no more threads were being exposed in the process. I have read about the rod of the strut rotating and did not do more than a few turns when I realized they weren’t tightening as they were supposed to. My main question is should I just leave it as they are showing more threads than the stock and should be fine or should I try to hold the internal rod and torque to spec?

I actually did the same type of mods 2 weeks ago. I bought a thread chaser for upper and lower shock mounts nut plates and ran them through a couple of times. Cleaned the after thread chase and installed all new upper and lower bolts. Using a floor jack to raise the LCA untill I could screw the upper and lower mount bolts in about 4 turns untill I reached the Ford thread loctite. Then I screwed the bottom ones in until the bottom strut mount bar is snug but still can move with light pressure. Then I screwed the top mount bolts in "evenly" until both are snug. Then I torqued each one top and bottom to 20lbs, then I finished torquing the bolts to spec.

If its not making a clunking noise, its probably tight enough. The weight of the car does the majority of the work to keep the strut in place. The top nut just holds the strut rod when the wheels are drooping.

If its not on a stock shock, you dont care about the number of threads showing unless you compared them both together (stock and new strut) when off the car.

anyway if the spec was 75 and you got 50 ft lbs its probably fine. Its not a large nut.
