If you have shipper cut the 2 metal top bow in half that should avoid a costly oversize shipping fee (usually 108" length + girth). You can insert a metal rod and reweld halves back together.
Raul in Mexico used to sell a vastly improved folding convertible top frame (Believe it had fabric too) on ebay for $500. You might be able to source one from him too. It will be heavier for sure and suspect cost has gone up.
