Weisflock,

I just ordered some contacts from Steve Young (The Pinball Resource) in Poughkeepsie, NY USA. I described the process in this thread and was pleasantly surprised how the contacts fitted perfectly:

Hope that helps.

Don't go by the machine name.
Read the whole thread mentioned in my response and order the Medium thickness blades and the corresponding sets of contacts (sold separately). Get the large copper/tungsten and the smaller gold contacts, just in case. Part numbers can be found on the PBR web site.

You will need to solder the contact to the back of the blade. The blade will fit perfectly in the plastic insulated stacks of the Recel machines.
