Thanks for the quick replies, it was actually me being kinda dumb, the 61 has an extra spacer up front that was on the real tight once we got that out it was good to go.
JHM- reason im switching the 61 for the 65 on the convertiable was for autocross, the 61 just had too much torque down low for my liking and with scca going to street tires mainly next year i wanted to put the 65 back on my car, the 61 is going on the convertiable as our "drag" car with some other mods
