Just Purchased Bike, noticing issues from previous lay down

[sapper]

Hey, im new and a novice rider. purchased a 2002 that had been laid down and accepted the fact that there is a bang in the front left of the tank and planned to replace it once i found a good used one. There are two stops on the frame where the front fork is housed that limit the left and right turing angle of the front end. the previous owner sheared off the left limiting stop and that causes the handle bar to turn almost into dent in the tank. assuming i replace the tank with a new one, i am pretty sure that the handlebar will have contact there.

looks like the limiting stops were built into the frame and was wondering if there are any ideas on limiting the turning angle of this front end.

i will try to post a photo this evening.
