Different curvature on the shifter handle, but everything else available as repro has them all listed as the same. Floor hump, retainer and bezel as well as the boot. NOT that I believe the repro parts as the gospel truth. But it would be a real puzzle if GM produced a separate boot for the same outcome. But, hey, stranger things have been seen...
Maybe someone with a parts book could look this up ? OR an AIM ? I think I had one before I moved, not sure where it ended up, as the '70 went right on the storage lift and hasn't moved since.
