Would anyone have a photo of the correct 1st/2nd shifter rod for 66 muncie. Or could you describe it. I think some of the information and photo's regarding this is incorrect in the 66 AIM. At least I found that to be true regarding how the shift levers are attach. Also Looking for a photo of the correct reverse lever. I understand the 64-65, 66, & 67-68 were all different. Thanks.

Jim, I will provide you pictures tonight.

Levers:

The one on the left is for 1964, Impala or Chevelle, they actually use the same linkage too. (in 1965 Impala lengthened the rods it used for Muncie as it moved the shifter mechanism rearwards)

Middle is for 1965-1967 Chevelle, Impala and Nova. The one on the right is for some 68s. ( I'm not exactly sure of the 68s)

The levers are held by nuts to the transmission, bolts are used for 69 and up. This is a common mystery for people using a later transmission in an earlier car.

This picture below is of 64-67 Chevelle Muncie shifter rods. (Saginaw rods are different) There are two sets shown so that you can see the bends. Most rods have a D stamped in them but in my experience there are about 10% that do not.

In 1965 GM provided two rod holes in the 1-2 and 3-4 levers. This was so you could select a short throw or long throw for shifting. A clever little low-tech option IMO.

The factory shop manual has a good procedure for adjusting the linkage. The drawings in the shop manuals and the AIM are vague. It leads me to believe that the linkage was supplied with the shifter already assembled and the line just attached it to the tranny or it was already attached to the tranny.

NOTE:
Saginaw linkage is different (rods and levers) the mechanism and levers are the same.

The BW T-13 shifter is different again (rods, levers, stick and mechanism)

Don't even think about using reproduction parts.:mad:...don't get me started on that one.

Thanks Tom, The shifter I bought was shipped today. From Photos and questions it appears that all 3 levers are correct. The 3/4 rod doesn't look right, he told me it had a D stamped on it indicating it was for a chevelle with a muncie. The 1/2 rod appears to be wrong. Hope I can find a correct ones.

D stamped into the rods is to identify the manufacturer (or maybe something as inocuous as "dayshift") like the S for A.O. Smith. Impala and other 64-67 rods have D on them, the Corvette rods usually have WM on them with the W on top of the M.

In 68 they started to stamp the last 4 digits of the part number on them.

Once you know what you are looking for, you got it made. People claim all sorts of bunk on eBay. It's hard to sort it all out. Took me a while...still learning.
