Which under drive pulley to buy/use?

[seningen]

4.5 months in -- so far so good -- no real issues except my water temp will climb a little if I am idling and I do NOT have the AC on.

I think the AC kicks up idle a couple hundred RPM and this is sufficient to spin the H2O pump enough to keep up with cooling needs.

Based on comments from the forum I went with a solid one, I also liked that it had
the same groove pattern and was a complete kit.



If I have any issues -- I'll post, but so far so good.

Thank you for everyones guidance.
