Hello, my first time posting on this site. I bought some CASE 400 lbs rear wheel weights to mount on the CASE heavy cast centers. I found out later (after I bought them) that you mount them on the inside of the cast centers. Has anyone ever mount them on the outside of the cast centers. This would be on a 2590 or 3594 type tractor. These cast centers have the 4 tabs which look likes the weight would inside of. I was told they may not fit flush to cast center therefore the reason for mounting on the inside. Any help appreciated as I have search everywhere and have found nothing. If possible photos would help. The weight is # 15 in the image and the cast center is #12
