Sorry, missed that. You may be able to get a replacment from one of the manufactures but proobably best bet is looking for a used system by searching the forum classifieds & ebay. I found this plate only
on ebay, not too cheap but it has the solenoids.
Also, regarding the second part of your solenoids need to be able to support 200hp so you may need to research that.
