Am I missing something here? Everyone is fussing with trig when all you need
do is look in Bentley 19.16

- raise vehicle approx. 40 cm (15 4/3 in.) at front under cross-member with
floor jack and wooden support or equivalent.

PS Hope this isn't in html or mime, if it is, I'm sorry, I'm just trying to
help.
