Well I just talked to the shop, and they advised the MM kit runs into trouble when the trans/bellhousing isn't stock. They advised they may need to use a UPR triple hook quadrant, and that if they could just adjust it, the fee would be about $125.
When I mentioned the McLeod clutch and the clutch fork sitting almost all the way back, he advised that typically you have to use a different pivot ball to get the correct adjustment. Dropping the trans means a fee around $500, which I feel is fair... probably put a new throw out bearing in as well. If I was younger and single I might try to drop the transmission myself, but with limited time (kids) it's not something I feel I can tackle myself right now.
