Unidentified Accelerator Control Rod with WM logo

[David L.]

Can anyone identify the accelerator control rod as shown in the 2 photos below? It measures 14 1/2" inches long with thread 1/4"-36 X 1 7/8" long threads. The "WM" logo is stamped about 2" from the non-threaded end. The slight bend is about 4" from the non-threaded end. I must have bought this rod at a swap meet. It appears to be N.O.S.

This rod is very similar to the 1966-1967 Corvette 327 rod, GM #3880168, which measures about 13 5/8" long and has the same "WM" logo and the same bend angle.

I have researched using the 14 1/2" length along with my vintage Chevrolet parts catalogs and found only one possibility....GM # 3913411 for 67 PASS., CHEVELLE (396, 427) (2nd design)(exc. Sp. H/Per.). The 1st design rod, GM # 3884868, is listed as 14 23/32" (or 14.72") in length. Most of the accelerator rods listed in the parts catalogs do not have a length in the description.

John,
The rod might also be GM # 3884868 as shown in my 1966 Chevelle AIM (UPC L35, Sheet A11) as the shape is the same. GM # 3884868 is described as "ROD, accelerator. control (developed lengths 14 23/32) in my parts catalog for 65-67 PASS. (396,427)(1st design) models. This catalog does not include Chevelle, Camaro, Corvair, and Chevy II models.

I believe that "developed length" means the length of a part that is stretched out straight. In this case, the length of a straight rod before the bends are made.
This rod measures about 14 1/4" to the 90 degree bend point plus about 7/16" from this bend point to the very end for a total of 14 11/16" or 14.69"+/-............14 23/32" = 14.72", close enough.
I now think that the rod is GM # 3884868.
