Welcome to the Stovebolt cool
Have you thought of shortening the studs that are already there?
Put some nuts on the studs down below the spot you want to shorten them to then cut the studs off. use a file on the edges just enough to take the edge off and remove the nuts to clean the threads smile

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!
