I have owned a 63 Riviera for 2 years now and the previous owner swapped out the original transmission for a Super Turbine 400 that was built in 1964. The transmission shift linkage is brazed to the shift shaft as you can see in the photo which I would like to correct. I am looking for replacement parts but I'm curious why this might have been done in the first place. Can anyone offer up ideas as to why someone would braze the linkage like this ?
that should be a shaft with a nut. I'd bet the shaft broke or the threads stripped. I'd leave it. if it's made it this long it'll probably last forever
Looks like a great upgrade, from a dynaflow to a TH400. Things like that take some work on the shift linkage (ask me how I know). That does look pretty solid, and I would leave it alone as long as it works well. Perhaps he made up the right geometry, but didn't know how to make a hole with 2 flats. Bruce Roe
