It is sort of a poorly worded sentence but I think he was trying to say the running gear is factory with the exception of the 5 speed trans. At least that is one way to read it.
How cool would that be, serial #383 with 383 stroker motor?
That car is a long way from being original. The body kit pieces could easily be removed. But there are a number of interior changes, like the center console has been changed and the guages are all white faced. A resotration would propbably be prohibitively expensive.
Perfect Hybrid material.
