Greenwater,

The Jag splines are larger than the MG/Heally/289 - roughly 73mm across the splines. I would hope that the 427 used the larger size, but I've never seen a 427 with wires. Because of lots of technical problems using the smaller spline adapters, I'm going to try very hard to use the Jag splines on all our subsequent wire-wheeled 289s, even if we can't get "AC" on the wing nuts.
