The rod that attaches to the carb has a different bend. The back half of rod or the part the front rod threads into is the same for small block and big block.

If anyone has pics of each rod that would be stupendous.  Are they interchangeable or no?

 The L34 /L35 rod shown above is for use with the earlier Quadrajets that used a rubber bushing w/plastic insert in the throttle arm. The L78 style was used on the later '67 L35's that used a Quadrajet but the throttle arm no longer used the rubber bushing. Both my L35's w/Q-jets (March/April 67) use the L78 style rod.

My 68 396/325 use's has L78 rod. Did some research 68 & 69 assembly manual show's the same rod for 325 & 350 HP as 375 HP. Also my 69 gm parts book give the same part's for all 68-69 396. Always trust my part's books over google. But found out 67 z-28 front rod uses different # than 68-69 z28 would like to know what was the difference.

Sport, A clue to look at is the difference in Assembly manual between the 2.  67 UPC Z28 Sheet A3 & 68 UPC Z28 Sheet A3.  Throttle arm linkage changed on the 3910 to the 4053. Ill have to look at my photos as I dont fully agree with the pic above on throttle rod applications.

Well if you want to be 100% correct...  67 Z shows a different part number for the front half of the throttle arm linkage vs 68 & 9 in the AIM.  The rear portion is all the same for all 3 years.  67 used a cotter pin and the 8&9 used e clips to attach to the throttle arm of the carb.

I was curious about the apparent throttle arm rod  front and rear portions component finishes as related to the photo from: July 1968 Car Life Road test Page 47

This is off one of my survivor cars. Carb rebuilt but Engine never out. Cowl Tag Date O5C. Hope this helps. ... Danny

 What happened to the pictures being cut off?  Maybe someone can fix it?
