Are there any compatible tanks i can try and find?I hate to agree with everyone else but I do . I do not remember EVER seeing a steel Ducati tank that full of holes and I have a history of soaking tanks in acid before coating them. Rarely do I see a pin hole those holes are HUGE!
Finding a better tank will be where you want to go. Even a dented tank will work and may be the best option. Find a mildly dented tank and have it repaired, while repairing have the tank hinge plate welded as well and you will likely have no issues going forward. You may put a want to buy on this site but your tank is one of the most sought after (if not THE most) because it is the tank plastic tank monsters also are looking for.
