<VV> FC van choke and Greenbrier weatherstrips.

I understand all that perfectly, so there is no need to keep repeating 
it. And whilst it's very kind of you to 'point me in the direction of 
the shop manual' I already know know how to read a workshop maual, but 
it doesn't show what I need to know. If it did, I wouldn't be posting 
queries on here!
But there still some things that don't quite add up. I do not have a 
"plate held on by two screws" on the firewall. The pic in the manual 
seems to show a plate held on by FOUR screws, but on closer inspection 
the bottom two may not be screws. It's impossible to see what they are. 
I do have two screws in the firewall, but no marks anywhere indicating 
the presence of a bracket in the past. It is not impossible that there 
was one there at some point though. If so, that invites the question of 
why anybody would remove the entire choke operating mechanism when it 
has manual choke carbs (of which I have four - two spares came with the 
The bigger puzzle is what has happened at the front end. There is one 
question that only GM can answer - why on Earth would they print the 
word 'CHOKE' on the dash and not have a hole underneath it for the 
choke, necessitating having to fit a seperate panel to accommodate the 
choke cable. That's very odd, to put it mildly.
What I am missing is any holes under the dash to accommodate a choke 
cable bracket. Surprisingly, the manual contains no pictures anywhere of 
the dash layout. But I did find an oblique picture in a different 
section that does appear to show such a bracket to the left of the 
steering wheel. I have the wiper & washer switches mounted there, 
clearly off a Spyder. So that presumably is where the holes went! I'm 
sure somebody said they were on the right?
The long and the short of all this is that you cannot have a manual 
choke with a Spyder dash. Yet that is exactly what I have! Maybe that's 
why the previous owner gave up, when he realised what a pickle he had 
got himself into! I do have the original dash, but it's a bit scruffy. I 
have found a nicer one on good old eBay & I plan to use the Spyder dash 
on one of my cars.
But at the end of the day it's still going to be easier for me to swap 
carbs than construct a choke mechanism from scratch. In the meantime, I 
just use a squirt of brake cleaner down the air intakes to get it going 
from cold, then it will run happily without a choke, which is just as 
well in the circumstances.
