I'm trying to figure out the interchangeability of some shifter linkage.

I bought a shifter several years ago that I was told was for a mid '60s 4 speed GM(1st picture). Just to look at it, it appears very similar to a '66 GTO shifter that I had in the past.
The other day I bought a 4 speed shifter that is supposed to be from a '66 Chevelle.
Neither of these had any linkage with them when I got them. After I picked up the Chevelle shifter, I mentioned to my neighbor I had a growing collection of shifters but no linkage and he said "I've got some extra linkage that I would sell from the '66 Chevelle I had years ago."

Would the linkage for these two shifters happen to be the same?
Just trying to decide if I should put it on the "someday" shelf with the GTO(?) shifter or put it with the Chevelle shifter when I resell it.

it seems pontiac is pontiac
olds is olds
chevrolet is chevrolet for linkage and levers and shifters

very little interchanges ,,, yah there is a couple things but from what I have owned
95% is specific to the car and year and model and trans used ,,, mounting plate ... levers etc

I'm not an expert, but I believe it depends on the shifter. If the shifters are different, then no - they will not interchange.

I was afraid that would be the case. But, I figured I should ask since all the shifters I have installed have been aftermarket and specific only to the transmission.

I have recently delved into this;
Apparently the reproduction stuff that Inline Tube makes is patterned after 1969(?) GTO parts - they sell it as a one size fits all.

I have found that there are three distinct variables for anything:
1) shifter plate - (forgetting the shifter handle receiver for a moment) this positions and angles the shifter body

2) shifter arms (transmission mounted); this plays key in the length and shape require for the rods

3) rods - generally unique for a given application; I believe that GM tended to stamp shift rods after (about) 1966 - but in my experience, even rods made after that may not have any stamping, or an abbreviated part number - or even the last digit in the rod's part number.

I think it all plays together because the consoles being division specific required the shifter "pop out" in a specific spot.

This one made me chuckle just yesterday;
The following image is of three Muncie three speeds - they are the same length as, and use the same shifter brackets as all pre-1970 GM four speeds.



The red arrows are pointing to the rear/lower shifter bolt location - lok at it's relation to the transmission's output!

The bottom one I just got, and found that it's more or less useless to me at this time - I cannot even mount an OEM shifter to it!
LOL.

??? hmmmmmmm

/\ the large output Muncie four speed first showed up in 1970, and was used for 1971+ cars;
The large output four speeds used a different shifter bracket, because of different mount boss locations, and is shared with the 1973+ BW-ST10.
I believe that the saginaw retained the small output, but do not know if the shifter mount bosses changed.

Oh!
And I just found out last night that the lower shifter bracket in that picture is sold by Hurst as being for a 63-67 Corvette with a Muncie
