Header install help

[standaman7]

I was trying to install some Jegs brand long tube headers (not my first choice, but its what i got at the moment) on my 69 sbc 307 and ran into the problem around the z bar. Passenger side went in pretty easy (just had to remove the starter to get it in there) but the drivers side wont sit down b/c of the original clutch linkage. I've read in other posts that folks have had to make several mods to the z bar and bar to make it work. I am trying to understand how i do that without destroying the linkage and making my clutch inoperable.

Or do I dimple the header as another option? trying to do what would be least path of resistance at this point until i can get some really good headers.
