I have a very early build ECLE (manufacture date of 5/1/2013). I had 2 small boards fail years ago, but all the light boards seem to be working fine since, although my collection sees very little play. Nevertheless, I would like to buy the 2.0 light boards to have them just in case. I don't see them listed in the WOZ parts on the JJP website. Are they only available if you call them? Is there anything different or any problems with switching out my light boards in such an early build machine?
