Need a Viscous fan complete

Hi all:
Since I put my new engine in my duster in June, I have had a few issues, one being it was overheating, I posted for ideas and tried a few, and now I have the opposite issue, now my car wont warm up, it takes bumper to bumper driving for approx 30 minutes to get it up to 180-190, I had an electric fan and no shroud, bought a shroud and a different fan, well that didn't fit not enough room, sooooo I went and put in a 2" spacer and went back to my old Flex fan, no electrics, (by the way someone from here told me to try that) so now It wont heat up fast enough for me, so my idea is the Viscous fan. Mancini has them new for 119.00 Summit has them for 115.00 I would be happy with a good used one if any of you have one, thanks...
