Do Hal Shocks Need any Modifications??
Well, it depends what you're doing. If you want to use the stock springs with them, you will need to buy or make modified stock spring seats.
Other than that, they should be good to go. One thing to remember when putting the upper mount on the shock, is to mark it in relation to the center of the lower mount of the shock. This way when you go to put the shock on the car, the 4 holes on the top mount will align correctly with the 2 holes from the bottom mount. Once the spring is on you can't really rotate the top or bottom too much if the mounting holes don't line up - the spring just has too much force, and you'll have to copress it again if anything needs to be adjusted.
