I need new top rails and caps for our Outback Melbourne pool. Top rails are each 57" long and I need 18 pieces for top and 18 caps. The caps come as two pieces. I did some research from your other pools and the closest item I found for the steel top rails was # 26336 @ $43.99 per piece. Please indicate if this is still a valid part #. We have a 33X18 oval pool and the pool manufacturer is from Australia and the pool name is melbourne. Thank you for any assistance you may be able to give with our problem. I did take pictures.
