Caprice parts into HX Van?

[DionP]

Hi guys.
The bloke I just got my HX Kingswood (dam) Panel Van off has just told me he has a complete 1984 Caprice that goes with it for parts. He has already put the front guards, bonnet and front end on, but he's telling me the rear axle is disc brake and I can put that on as well. He says the seats don't fit, is this because of the bolt pattern, or are they bigger/smaller? Is there any other bits I should be looking at swapping off the Caprice onto the Van, or are they just completely different beasts.

Thanks, Dion.
