I've just found an exact replacement for the latches for my 84 Excella and want to pass it on to all that are in need.
In late 2008 we went to the factory and were told they are not available any longer. But I've just ordered 10 of them from Lee Valley Tools - Woodworking Tools, Gardening Tools, Hardware
at $2.30 each (stock# 01L01.01
) online through their catalog plus shipping of $11.50 from Canada.
This has been one of those great days as I also found a replacement door handle from one of the forum members (John Burkey).
