I just purchased the Flex-a-lite Mdl# 292 (http://www.flex-a-lite.com/auto/html/27inch-electric.html) electric fan and it came with “Universal” brackets which suck and they wont fit my 90 K-5 Blazer. I need some assistance from those of you who have this fan installed in there Blazer on how you fabricated mounting brackets. Picture would be really helpful too. Thanks a million. Dan..
