thanks guys, its been a journey with this one. starting with posting on every forum looking for one, many weeks later someone has one and PMs me. the clean-up of a hundreds of parts took a week. then the build with no instructions. so hours of research to find the location of parts. Over 3 weeks later here we are in the build and it's in its final 2 days i assume. whew.
One part broke yesterday. the R2 unit's fiber optic strand snapped off after weeks of handling. not the end of the world but i'll see if there's anything i can do.
