Craig,
That is sharpe. Your attention to detail will really pay off. Has Mark given you a timeline as to when you can expect your car back from MDA ? I'm in the process of purchasing his 331 stroker and I've got the same 930 gearbox mounting issue you have. I think he will make two sets of mounts at the same time, one for you and one for me. I need it done before i take delivery of the engine among other things.
Cheers,
Martin
