I've been refurbishing my last Ellis-Briggs and run into a little problem. Three different rear derailleurs (NR, Jubilee, off-topic newer Campy "Rally") that I've tried all want to run into spokes on the top cog. At first I attempted to deal with this by using a freewheel spacer, but now it really looks like that gap is too large. Now I'm suspecting that the drop out is bent in a tad, thereby angling the der cage in too far.
So my question is: what is typical minimum cog-to-spoke spacing (70's era components)?
