I'm looking to sell or trade my RBTA's. 45 a piece or trade for SPS or Zoas. I have 4 that have split from the original over the last two years. They are all fairly big, approx the sidze of a soft ball and look healthy. The only problem is that they look welded to my LR. Im not sure how to get them off. Please let me know if there are any trick out there. I'm located in Northern RI. Free all day Wednesday if you want to come and check them out. I am open to selling the pieces of LR that they are attached to if interested.
