Glad I could help Jim. If Cabelas flops you can also try
WWW.McMaster.com. The flying wires on my Tiger Moth are functional so I used streamlined wire from Nelson Hobby. Got the clevises from Mick Reeves in England. If I ever get back to working on my P6e I will probably use the laces you are using. They are readily available in craft stores since it's the same stuff crafters use to lace up hand made articles like purses, pouches, coin holders etc.
