rear disc brake conversions and E brake Early A

OK I have been thinking about going with the new 11" rear Wilwoods disc for the rear of my 64 Dart. I think this is a decent size brake and a good fit for a lite early A body. In the past they offer the 12s and up sizes. I am running 15" rims so no issues. Car is street street not a daily driver but I think the racing rear disc are a no go even for little street use per wilwood too.

I just need to make sure that he 8 3/4 is the standard popular offset etc. before I place the order for the right kit and I will get blank hats and have them drilled for the small 4" pattern too.

My question is this. I ran the 3" TTI exhaust full to back on the 416 fro mthe TTI headers, the factory E brake cables have no room, and I can not see how to make them work. The relocation of the guides etc are i nthe way of the pipes.

It would be nice to get the rear disc with the E brake built in, and from what I understand then you use the factory E brake cables etc to make it work.

But if I went with a non E brake rear disc from say Wilwood is there any other type of e brake I could install?

I know in the old days I even saw a large drum brake on a drive shaft.

Just curious is there any thing else i can do since I can not see a way to make the factory E brake cables work?

thanks guys :)
