Carb return spring for 67 L78

[big iron]

Does anyone know the color of the 67 L78 carb return spring?
One end goes the carb arm  but where does the other end go ( to the coil bracket or the valve cover). A picture would be great!!!!!
Does anyone have a picture of the 67 BB accelerator lever at the firewall and what was the finish?

Did some research and this is what I found:
67 All 396,427 exc. PG ........................... 3913415 Black   67 AIM L35 A11
67 302 ................................................. 3910965 Yel.    67 AIM Z28 A3
68 Pass,Chevy,Camaro 302,396,427 .......... 3923501 Grn    68 Aim L35 A10, Z28 A2
69 Chevy,Chevelle, Camaro 303,396 .......... 3950210 L Grn  69 AIM L35 A8, Z28 A8

The 67 L78 uses the Black spring but where does the spring mount on the coil. Does it go over the long screw that tightens the bracket up on the coil , like on the 69 (L78,L89)or does it use the hole provided on the coil bracket? Buy the way does anyone know why the 69 is done that way???
John Z, found some info that indicates that there were 2 throttle levers used for the 67 BB up to 2-8-67 3879422 after 2-8-67 3912599. If this is is true, do you know the reason for the change?

I think you use the same carburator as the Z?  Do the L78's have spark plug wire stands?  The Z's spring goes to the wire stand, but I know there is a tang on the coil bracket too.  I looked in the AIM but didn't see where a spring went.

The index sheet for L78 (sheet A2) indicates that the accelerator controls assemble the same as L35, and L35, sheet A11 shows the return spring anchored at the coil, but it's not clear from the illustration whether it's on the coil clamp screw or on the tang on the coil bracket.

Plug wires also assemble the same as L35, shown on L35, sheet A6.

68Z and JohnZ thanks for the reply.
The 67 L78 uses the same type carb (Holley) and does have a wire stand with a hole. The hole on a BB is used for the return spring on auto trans. throttle control rod equipped cars (see AIM M35 A14.5). The 69 AIM Z28 A4 shows your application in better detail.
I think I found the reason for spring attached to the coil clamp screw (69 AIM M40 A9). Looks like this was done on (M40) TH400 L78,L89 (Holley) equipped cars because of the space limitation that the kick down sw. created. I wonder if this holds true of the 68 350HP (Holley) w/M40? 
Thanks again.
