Hi Tim,
Point taken on the length of the document. When I put the Warmaride one together, I ended up having to talk to a lot of the FE/FC and EJ/EH guys. They were great to work with

, and I found that a lot of the info is common. I guess I felt I should keep their info in given the help I got. I'll try to cut the washer one down to size.
The reference to electric washers on EK's came from the 20-year (FX-HR) Master Parts Cattledog,which lists the following:

This would infer that the EJ electric washer motor and pumps were also offered on FB's and EKs but with a dedicated FB/EK switch/lead and nozzle (assume it was an EK bonnet type as the EK's wouldn't have had the drilled/tapped windscreen washer pivot arm spacers). It's just one reference though - a lot of the stuff I have seen in different GMH and NASCO brochures can conflict (especially the line drawings)... part of the fun for me is trying to decipher the history (as an anecdote, the early FEs used the FJ washers before NASCO released the proper FE ones...ooops... getting sidetracked on other Holdens again!). I'd love to hear from anyone who has seen an EK with (original) electric washers... I was hoping Smooth might help out but so far he has been silent too.
