Opel is an M20 box! I assume you mean Aussie 4spd M20 (3 x different ratios in these too). Just copy an LJ fitment of an aussie 4spd: bellhousing, clutch arrangement, crossmember, tailshaft, speedo cable etc.

As Byron has said, we assume you mean an Aussie M20 not another Opel M20, but either way, no problems, because both were fitted to LC & LJ from the factory.

You will need the tailshaft, crossmember, speedo cable, bellhousing & clutch from either a 3-speed column shift manual (M15) from any LC or LJ 6-cyl or Aussie 4-speed from a late LC or any lJ.
Clutch linkage is the same & will bolt-up to the new bellhousing.

If the car is a 6 cylinder without an Opel box, the crossmember, tailshaft and speedo cable will be those fitted to the car already.

If 3 speed, just remove the 3 speed box, cut hole in floor and insert aussie 4 speed. If auto, will need the clutch pedal and linkages, short out neutral safety.

Will need to re route green reversing wires from column to centre console if column auto or 3 speed.

Console is available from rares.

Hope this helps.

Warren, the way I read his question, he currently has an Opel box. He typed it with a lower case O (opel, but should be Opel).

Thanks for the replies,
The vehicle (LC)currently has a Opel gearbox in it and was thinking of putting in the Ausse 4 box. So are the tailshaft & crossmember required to fit the Aus 4 speed, different than the one already in the car?
