Hi Wise, Thanks for the link to Strathcon. That's where I shop here in the Comox Valley, Vancouver Island. I think I drive those guys nuts sometimes looking for some odd solutions to fastening issues I've had. And stainless steel too! I could spend a lot of time and money in there. Better than any hardware store I've ever been to.
Hopefully others in B.C. with fiberglass trailers have access to this store. Great advice.
