Tom, No. The Lp2 wheels are wider at the rubber / rim. The hubs are the same and use the same axles and bearings. They could be used but the tracks wont be stable. The track links are the same except that the horns that guide the track are wider on the Australian carrier. The LP2 and LP2A used track that was similar to the Vickers Light Tank Mk6B (The Aust. track has a short pin located with a lead plug and had a small hole on the opposite side only to enable removal of the pin. The VLT had the same pin arrangement as your Canadian carrier)
On the side rollers. The Australian casting that mounts to the hull sides, make no allowance for the angle iron at the floor in you carrier, and the holes are positioned differently.
The pin through the roller has a BS thread while the LP2 has a UN thread. The Aust. LP2 also is drilled with a grease nipple while the Brit / Canadian carrier has a vague "dribble" arrangement that relies on "hope" (actually I think the bushes (2 each side) are maybe "oilite", or sintered bronze that were pre soaked before assembly and relied on a bit of residual oil from the grease that drops on the roller and cross shaft. The roller its self may fit.
The cross tubes are different lengths.
