OK - I am ready to buy - except for one not so small problem - the height of my garage entrance. Toyota lists the height of the F J Cruiser at 72' (no roof rack) - but that is not correct - my dealer and I measured the roof at the highest point and it is 73". And since my garage entrance height is only 72 1/4" and with an inclined driveway entrance I will need the height of the F J Cruiser lowered by AT LEAST 1 1/2 ". No - I can not adjust the garage door. So my question is: Can the suspension of the F J Cruiser be lowered by 1 1/2"? If so, what all is involved?
