Rattle in Stick

[unplugged]

AT 4000 RPM I get a pretty big rattle in the stickshift. I got under the car and took of the plate and inspected the nut holing the stick in and it was tight. I recently had the Ring & Pinion replaced in the rear end and I lost 4th gear.

Could either of these be the cause?

Any suggestions on how best to track it down?

Thanks

it is most likely the bushings in the shifter extension. this is the chrome part that sticks over the shaft from the transmission, there are 3 rubber bushings and 2 nylon pieces inside
