ls400 swap

this may have been covered already but i cant seem to fin any posts of it, if so please just point me in the right direction. Basically im trying to figure out if both of these front ends are interchangeable, im guessing they are since the have the same chassis code.

pretty sure you can spec wise the chassie didnt change much if at all so all you need is fender,bumper,hood and lights. if you wanna get tech radatior support ect.

so radiator support has to be swapped as well?

i'd be very interested in those info as well!
