I recently fitted 2 Recaros from a VX into my HPE.
During my research to find a couple of missing plastic parts I realised
that the seats I had were very similar, if not identical, to period Fords.
The sliding mechanism varies but the seat frame remains the same. And
you're more likely to find a pair that tilt for rear access.
In any acquisition, the sliders will be suspect. I used replacements from
eBay, and had a good outcome. Always select the double catch type.
I had to make custom brackets to increase the width, but you'd likely
have to do that anyway.
