Carb and Divorced Choke issue

Hello All,

I have a 74 Valiant Brougham with a 225 Slant 6 and I am having an issue identifying my carburetor and was wondering if anyone could offer some insight. The only identifying marks on the carb are as follows:
6R
4360
B

From what I have found it is a Holley 4360. Unfortunately the only Match I could find online was for a 4360 and 4360 C 4BBL which I do not have, as my car is all original. http://www.carburetion.com/images/carbid/holley10.jpg

The question of the model number of the carb arose while I was searching for a new divorced choke assembly. In taking it off the manifold I noticed that the coil is very rusted. I cannot find a replacement part anywhere thus far. The ones that I find look like mine but they are a different part number. My part # is 6676 followed by a 76 underneath that. I want to use OEM parts because I dont want to deface my car with cheap foreign garbage. Any insight would be greatly appreciated.

Thank you for your time!
