Need help with getting the correct 340-6 Kickdown Linkage rod!  I have purchased 3 used rods from various sources with a promise that they were for a 340-6 setup.  None were correct.  I only needed the rod, but I had to break down and buy the $350 kit which contained all the linkage parts.  With great excitement, I installed the rod and it hit the firewall at about half throttle!  I then borrowed a friend's  original six pack kickdown rod from his running T/A.  I installed it in my TA and it fit perfectly.  I took some photos of the two rods and it can be clearly seen that there are major differences.  I thought about heating and bending the repro rod, but it is so different I would probably end up destroying it.  Does anyone have a suggestion as to where I can get a correct rod?  Very frustrated!!  Thanks!  (I hope the 2 photos were attached.  I checked the preview and they weren't there!)

Is it different from a 340 4 bbl set-up ?

I had the same problem when I did a 73 340. Bought 2 and neither one would fit. One had the correct bends but was short so I cut it and welded in a piece, ground it and painted it and it looks and works fine. Nothing like one size fits all with Mopar!

Yes, they are definitely different from a 340 4 barrel.

I'm surprised that it's a one piece system. I thought the 70 used the 3 piece setup. At least the FSM shows that.

That's interesting, I can't find anything in the parts book that calls out for a different rod for the 340  six pack engines. Do you have the part number :thinking:

I don't have a part number.  Most 340-6 stuff isn't in the parts book.  It seems that the AAR's and T/A's were last minute projects and were too late to get included in the book.

Is there a list somewhere of unique parts that the AAR/TA's had, and their numbers ? The parts book I was reading today, has 340+6 parts listed, just not a different part number for that rod  :thinking:
