Guys thanks for responses and ideas.

Phil, very interesting to hear that these rubbers were often cut from whatever old rubber they could find. I guess I could also do that, but I thought it would be easy enough to find some newly made rubbers at one of the parts suppliers.
I haven't had any luck with finding the rubbers at Chev of the forties or the filling station, or maybe I am not looking good enough. Will have another look this weekend.

Thanks again,

Alex
