the second (as far as I remember) has the early grille arrangement,
I've given Neil a shout about the one he's offering anyhow.
Don't be put off by the grille arrangement. Back in the day I had an early Beta with the series 1 interior and raised bonnet centre section that I upgraded to full series 2 spec with an interior transplant plus the later grille/headlights/surrounds. The early bonnet uses flat hinges but the later one a step down Z shaped hinge. The mounting points are the same and the hinges interchangeable to suit the grille you've got.
