Bit of as long story, but basically picked up just the body pretty cheaply on ebay and married it to an old spare chassis I had.
That chassis I got in another scrapyard a year or so back, along with a Pontiac Firebid with a broken chassis (snapped in half through
the back wheel mounts. As it turnes out, the Pontiac and Datsun chassis are identical, apart from a screw hole at the front where the
chassis is mounted to the body. So I drilled a hole in the appropriate place and used the Datsun chassis to complete the Pontiac. Once I
picked this car up, I switched the correct Datsun chassis into this one, and am repairing the pontiac chassis to install on the Pontiac body.
