Hmm, not criticising my friend , but this is salvageable . . .pack up the back of the motor and move it sideways slightly . . . the UJ your using is a poor copy of a genuine one, there are good ones out there , you need to have the block pins sticking up ABOVE the plastic sleeve to avoid them climbing out of the holes and coming apart under heavy loads . . .
A single UJ will NOT take care of major alignment problems , the centre lines of the motor and shaft need to intersect in the middle of the pin block THEN you can swivel one from the other & pack accordingly , major misalignment will need TWO UJ's back to back to compensate, even this would be limited in it's movement .
Been there , done this (haven't got a t shirt tho) , now I use a dummy alignment sleeve , same length as the coupling, bored to fit the motor shaft one end / propshaft the other end , you could even make one up out of any tubes you have that will go together , need to be a slide fit tho' . . .
