ME128 is for 1951-1954 1/2 ton; so, unless they sent you the wrong/earlier bushing, or you have an earlier rear-end/torque-tube, that part should fit your 1953 1/2 ton.

It is a tight fit.

I freeze the bushing before installing it.
And, I check/clean/smooth the mating surface inside the end of the torque-tube (it looks like you have done this).

I have not used a JC bushing - mine came from Patrick's.

Maybe someone else can help?
