Re: Packard Engine to GM Auto Transmission Adapters

Am curious how you are going to hook up the GM throttle cable. Believe Bendtsen's original instructions -- at least on the V8 -- had a tab welded somewhere on the accelerator linkage at the carb in order to attach the cable. Seem to remember one or two saying that proves to be tedious or hard to attach on the piece of metal available. Not sure if it was due to size of metal or because of the type of metal the linkage is made of. Another installer decided to attached his cable by making a bracket to clamp the cable housing I think to the firewall and drilled a hole in a section of linkage on the drivers side.

Instead of a drilled hole, would think something that would slip over an existing piece like the accelerator bracket on the firewall or better, would be to keep the existing throttle linkage on the engine and use the lever at the end of the rod on the right side of engine where the current throttle bar down to the Ultra attaches. Unless something in the geometry of the old linkage would mess it up, think the engine place would be simpler and more easily adjustable on the V8. Not sure on the S8 but If it was a clamp seems like it could slide on the throttle rod lever to find the precise point the GM transmission is supposed to want for the trigger and then locked own.

Use the existing bolts for holding the bracket but would need to make sure some way the housing bracket and cable mount angle could be twisted or moved so the housing and cable would be in a straight line.

If you can come up with something easy to do maybe you could take a few photos so the next guy doesn't need to reinvent the wheel.
