This choice would depend on whatever work I�ll be doing !
I don�t like to have the bus on stands if I need to get really good
clearance, like when I did the engineconversion !
THe Volvoengine needs some extra space to slide in underneath so I used 12
wheels, two under each front and four under each rear wheel of the Vanagon !
I also tried to push it down before I started the work since I knew that
there had to be some rocking around, getting the WBX out, moving the gearbox
and lifting the I4 in place and having such a heavy vehicle on stands (on
gravel :-) ) for a longer period felt unsecure
I always use stands when working on the brakes and ramps when changing oil
though so I think you could pick whatever you have that feels OK as long as
it works along with the job you�re about to preform
If you don�t have the ramps, you could make them yourself out of 2x4, 6x4 or
whatever you have, then you have the chance to make�m as high as you need
too, just remember to make them wide enough so they don�t fall on their
sides with you underneath
Safety first !!
