There are 2 (one is in indefinite retirement) J30's in Lemons. Pi-Nuts and Team Infinniti.
I drove the now parked Pi-Nuts car which had a 300ZX Manual transmission swap. It was a great A class car.
See if either of them can get you some pictures/ find out what they wish they had done diffrent.
I would recommend however to find a local cage builder for the job. They can see in their head what to do like magic.
