The van I have is a HX in mint julep with a 253, 4 speed, 1950gvm and 2 seater. I thought I had my dream car but I now think it's an XU4

There was nothing original left by the time I got it, however there was no evidence of it having a floor shift. Unless of course the whole thing had been re-shelled by the time I got it.

I better contact holden historical services myself.

Buickrat, I found they came up first when I did a google.
