    Looks like the exact same linkage found on my big block swapped C10.

    All my swap needed to play nice with a TH350 was a Trans Dapt #9620 bracket to attach the kickdown cable to the linkage.

    This is my 350/TH350. Maybe it will help.

    By the way, does your accelerator linkage loop around the motor, or does it come straight from the bulkhead?

    If from bulkhead is there a little loop before it goes to the carb?

    Looks like the correct linkage to me. If it's not, it'll at least work and should work fine.

    Cable has an S shape from firewall to cable bracket.

    My original throttle cable, which had a broken fitting, was a little shorter and did not have any S curve in it to reach the linkage. When I bought a replacement cable it was a little longer and needed the curve in it to fit the space. I don't know if you can still buy a true original length cable.

    I got a new one from LMC that was about 4" too long. They did not want it returned and refunded my money. So, I still have it in storeroom. You can read about it here if you like.
