i pulled the fan shroud before starting. try a search - i know there are some real good threads out there. Jrichker has posted info with bolt specs and all that too. i did a write up on a thread i started about it, where i outlined how i did it, but i cant find the thread. if you come across the thread, read my last post - i wrote up what worked for me.
get some vert or poly mounts. the vert mounts are heavier duty (interlocking) than hardtop mounts- and on a vert, necessary. they became standard for HB's, etc by 93, IIRC. poly is real nice, but 3 X the price of LLT oem replacements.
good luck.
