Hello,
Rancho has spacing of holes 4 x 98 mm - it is the same as for example: Alfa Romeo 33, 145, 146, 155, Fiat Uno, Tipo, Bravo, Lancia Delta, Seat Ibiza (-> 98), Skoda Favorit, etc...
Peugeot has 4 x 108 mm
Renault, Opel, Nissan, VW etc. they have 4 x 100 mm. Some people say that 4 x 100 mm can be mounted to 4 x 98 hub, but I won't try this because I don't believe that it is safe.
Diesel engine in Horizon and Solara was 1,9 XUD Peugeot engine, but problem isn't if it will fit into the Rancho, problem will be with everything else, as for ex. fuel tank, axle shafts, exhaust system - You will must to do it Yourself and it is a lot of work against doubtful result
