i just found this page, lol!  I still have parts of the chassis, probably 90% or more?.  I'm 66 yr, my dad bought it for Christmas when I was 15 yr.  I already had the V-8, it did mate up perfectly.  It moved and was able to shift the manual 3 speed.  He always said to trash it, later in years because it broke throughout the years.  I told him it was probably the best present, he'd ever got me!  He's gone now, can't seem to trash it!
