Hi Conrad,
I put the new clutch in a few weeks ago with no problem. I bought a good trolley jack and then cut two 200mm by 200mm 10 mm plates, one bolted on top of the jack, the second attached to the other plate with two 100mm hinges. This made it possible to lower the transmission while changing the angle and still having the transmission firmly strapped to the top plate using a standard ratchet strap. This made it quite easy. I changed the clutch in my previous 83 hilux around 1992. I can't remember how I did it but I think I may have just huiked the bugger out by hand. Thirty some years late I am a bit more cautious and less strong and also less cheap. The modified jack was well worth the investment. Thanks again for the advice.
