Suggestions for replacement grill fabric

I'm restoring and upgrading a pair of SDA1 signature speakers. I intend to wrap the cases in a new quarter sawn cherry wood veneer, and I'd like to replace the grill fabric with something that looks original. Any suggestions as to where I can get a quality fabric would be appreciated. Also the grill clips are in bad shape and need to be replaced, so suggestions would be welcome here ,too! Thanks!
