    87 T1 vs 88 T2 crankshaft timing belt sprocket

    As I am adding AC to my 87 Sundance from my 88 Shelby Z, I need to swap the crank pulley. Ya that should be easy right? Well not really...
    The 87 used a four bolt torx pattern vs 88 five bolt torx pattern




    Not only that but the sprockets are very different as well

    the 88 is on the left and 87 is on the right and a different puller is need for each as well.

    Yep, and then 89+ is a different beast too. I might have a pulley, I'll look tomorrow. So you need a 4 bolt?

    Too bad you destroyed the 88 sprocket.

    Thanks Turbovanman for the offer to help.
    My post was an FYI, as I have the parts and they are installed.
    the 88 sprocket looks worse than it is. It was fully useable without issue.
    the previous owner's of the 88 mechanic hacked up nearly everything he touched.
    I had the 87 sundance T1 since new, so it is in very good shape. I expect to install the KH brakes today
