I am looking at getting a set of waffles they seem to come in 3 common thicknesses - 30mm,38mm and 50mm. I want to use them for a 1984 Landrover 90 (V8 not that i think it matters). I have no idea what the weight of the vehicle is, I would guess 2.5 tonnes. What is the minimum size I should be looking at, I have heard that 30mm isd not strong enough, what about 38mm?
Thanks for any advice.
