I am in the same predicament, but I found one supplier that has them in stock. mine should be here friday. Dreamers is the name i think ??
Thanks for that name. I had never heard of them before but I found them and am waiting for them to confirm whether they have any.
Meanwhile, I will be trying to fix my broken one thanks to Steve H's kind offer. It looks to me like it should be relatively simple. I'll be needing another set soon for a 51 Suburban so either way it works.
