6-v8 Swap
Mick I don't think the 75 center link will fit the 65. Too wide.
The 65 K-Members are the same for the /6 and the V8. A set of stock 273 mounts will do the trick to mount the engine. Some of the 65 and 66 models, even with the /6, came with the dropped center link. Have a look here, second page, and you can verify which link you have now. You'll also need the driver's side 273 exhaust manifold in order to run the V8.
