here's 2 possable options to use the flogged out carrier...
standard bearing 6304 20/52/15

1-
Put a 30mm bearing in 6006 30/55/13 is 3mm bigger in dia
so the housing wil need turning out 3mm & a spacer sleave
machined to press into the bore to bring it back to 20mm...
this bearing is 2mm narrower than the 6304 but the bore spacer
could be made with a 2mm flange on it to make up the 2mm..


2-
16006 bearing 30/55/9..
only being 9mm wide you could bore the depth of the housing
to 18mm to take 2 bearings... have a new spacer machined to
sleave the bore down to 20mm as well as replace the standard spacer
but go though both bearings..

The internal spacers will need to be a indeferance fit "press in"

hope this make sence to yer......

just a pitty you arn't closer as I could do the machining for yer...
