Well after a wiring cluster-f**k, i pulled all the wires out, and continued assembly and will save the wiring until just before i'm ready for primer & paint, hopefully it'll go smoothly then because i won't be able to see what i'm doing at that stage of the assembly. I attached the top rails today! probably be awhile before i work on this again, need to find / fix a mysterious oil leak....
