Hey guys, hoping you can help me here. I've been looking to start CAD'ing up the parts I think I will require in my build so I can then fiddle about with them in a nice assembly. Trouble is, I can't seem to find the dimensions of the first part I'm looking at doing . It's the runners here: fl15ca-z0 either FL15CA or FL20CA would be good to get me started. Orrrrr, am I looking at the wrong type of runner and there is a really common one everybody uses that I've missed?

I did try the search button but couldn't see anything for those part numbers.

Cheers!
