I have a 1999 Alliance RIB that came with the boat. I would like to get some new grab handles for it but I have not been able to find much information about them anywhere. Are they still in business?
You shouldn't have to worry about brand specific parts. If it's hypalon or PVC, you can glue new attachments on that you buy from any of the suppliers. It's very common for the white water rafting folks to add tie downs and handles to their rafts and kayaks.
