Drew your original rear ujoint was 2 5/8 and the 741 is 2 1/8th You did buy a joint that was 2 sizes right? And when installed, it shouldn't be tight. No ujoint should be tight. You didnt drop a little roller pin sideways did you? Happens all the time to a lot of people. The clips go right in when you have it all correct and it will be centered automaticly since there is no room for side clearance
