If your thoughtful during the build process you should be able to build a car that will pass sva and not need changes after.
I personally think it’s a good idea to keep all the bolt covers etc on the front end. a) Because they keep evil rust out and b) should you hit someone you have no comebacks in relation to the cars safety.
As mentioned above if you have a serious accident and people are injured, it won’t matter if it was your fault or not. Investigators will go over the car with a tooth comb and throw the book at you if it’s non compliant.
If changing something can hurt someone other than you, best not to fiddle. If it can only hurt you that’s your choice so go for it.
