I ca'nt speak to an SRT6, I understand they are a bit tougher - but I changed mine in the SE twice now (the first replacement went bad in two months).

The first one took me almost 2 1/2 hours. But the second one took only about 45 minutes. It is NOT hard to do at all. Wrestling it out takes some patience, and I lined the frame of the car with cardboard to protect the paint - but it really is not hard.

Remove a battery cable and secure it so it can't come in contact with the battery post first. Then, Take the Engine fan assembly. THen remove the belt. Have a metric and Star socket set handy and you will be fine.

NAPA had an alternator for me for $220. Now, it seems that 04-06s used a Bosch Alternator and the 07-08s used a Valeo. Yank the bad one out first and see what you have before you order one! The configuration on the back varies a little but electrically they are the same.

On SRTs I am told you must transplant the old pulley to the new alternator but on the N/As that is not a concern.
