LAW75, good luck with your concours event.
Here's what I see needs to be addressed (I've numbered them for further discussion) to be concours correct:
1) Bumble bee wire not correct
2) Rubber Elbow crankcase to engine should be painted engine green. (Would assume clip too)
3) Brake booster hose is one piece
4) Clip that the holds the front carb cable should be all metal
5) Black carb cables shouldn't have any printing
6) Red wire has a blue plastic crimp on the end, not correct, plus it shouldn't be ground to the harness clip.
7) Black wire is grounded to the same place as the red wire, wrong place to ground it.
8) White wire from the voltage regulator doesn't run where it currently is.
9) Hood latch spring should have a black plastic sleeve
10) Hood connecting lever to slider rod, there should only be one
11) Hood rubber buffers, the two front ones, the split rivets are facing the wrong way, should be bent over too.
12) Brake/clutch can, missing decal, "break clutch".
13) Missing the hood rod support bracket (spring attaches to that also)
14) Missing the rubber tie that holds the capillary tube to the heater to return pipe hose.
15) Fan shroud was painted red with a brush, so it should show brush marks. (Concours judging)
These things I'm not sure about, other will hopefully chime in.
16) Hood rubber buffers, does the rivet go through both sides of rubber buffer, or is the rivet head inside the rubber channel? Rivet shaft exits out the rubber on the engine side, the ends are bent out.
17) Rocker cover cap nuts painted engine green or plated?
18) Radiator cap, looks aftermarket, OEM I think had something different stamped on it
19) Vacuum pipe, is it bent correctly, shouldn't it be held in place with clips and should it be copper, steel or painted?
20) Should the reinforcement brackets for the throttle return springs and the front carburetor cable be painted black, engine green, or plated?
21) There are two black wires exiting under the heater blower hose. (From the heater?) One wire looks like it's grounded to the harness wire clip, not a grounding place. I don't think those wires are run correctly to be seen the way they are.
22) Should the bolts that attach the hinges to the hood be painted car color? They are pointed the correct way, nice.
Some things I've mentioned may not be correct, others please point out any misinformation I've referenced.
