After seeing the damage a fellow TR driver has done to his frame thinking he could use a floor jack and jack stands under any part of his frame, decided I would scan and post the page from the shop manual
it would be nice if you could just jack them up like the NASCAR guys on tv. the frame on my 78 Ford LTD2 was fully boxed and made out of 1/8" steel, so i could just jam the jack under the middle of the door and jack it up just like the NASCAR guys. it saved so much time putting it up on jack stands compared to my usual jack points on every other full frames rwd car i've owned- the engine crossmember and rear axle center section.
You can put the jack on the K-member and rear diff? I've always put the jack and stands under the corners of the frame just inside of the wheels (the cross hatched areas).
