140 carb linkage

I could use a favor. I'm assembling a new 140 engine & have a "basket" of carb linkage parts. Could some of you guys post some pictures of their secondary linkage on the engine ? Also, indicate if what you are showing is 1965 or 1966.
Thanks in advance. Doug Ward

Maybe this will help. Early and late.

Can you tell us which crossover throttle linkage you are using? Is it the early 65 type pictured below that has a long curved bellcrank slot on each side used for engaging the secondary rods? That is a good place to begin to identify what you have.

Doug, I sent you the later style secondary linkage and crossover shaft with the spring loaded secondary links. Didn't I include a sheet from the parts catalog (page 3-13P) showing a close-up picture of the linkage? If not, I'll try to scan and post it.

Thanks guys, for the fast responses. Don, I did get the illustration that you sent, but the scan here on the forum is much larger & easier to read. Dave & Seth, I now know that I have the later linkage. I don't have the slotted early type cross shaft. I mainly needed to know what the differences between the early & late designs were. Thanks for your explanations. I have the parts all mocked up on the engine I'm building & I can see how I assembled it incorrectly in a couple of places.
FWIW, I know that some of you will think I'm a little nuts, but I am also attempting to use 1961 manual chokes on my system. My 1st Corvair was a brand new 61 Monza & I really liked how the manual chokes worked. It will be cool if I will be able to use the manual chokes. I have all the parts needed to put in to my 65 Corsa, if I can get it all working on the mockup engine. Doug Ward

OK guys, I got my late design 4 carb linkage pretty well sorted out now on my mock up engine. AND, the 61 choke linkage is gonna work too. I had to make a couple of small modifications to the accelerator pump arms so the choke mechanism would clear it,& had to bend the choke brackets down for the same reason. To mount the manual chokes, I just cut the mount off of the 61 cross shaft to fit under the regular cross shaft piece that screws to the carbs.
This is an interesting project. If your'e interested in it, I'll keep you posted. Doug Ward
