i just installed mine. these do not fit like they do with the stock rad. i'm using a custom 3 core rad and its has some complex fitment issues.

as for installing on a 96 and older, work on trimming more out for around the rad hoses and area for the oem trans coolers, as well as get a better mounting system. the upper and lower lip for oe mounting options are not as accurate as they should be. both of the upper and lower mounting holes were off by about 1/8th of an inch. and finally being an aircraft mechanic and quite mechanically savvy, i did fine with installing these. but you may want to include some install instructions and a wiring diagram.
as far as performance goes. these things rock. 110* day with all aux on and idling for 45min and never reached over 185* even with the ac on. now i can't give all of the credit to these fans as i have an aluminum rad and huge louvered hood panels but for the most part these fans are awesome. well done. i'll have pics if anyone wants some ideas on how to install these things or wire them up.
