DIFFERENTIAL COLLAPSIBLE SPACER (NO FILLER PLUG), SPRITE AND MIDGET

I am considering using taper roller bearings instead of the standard ball bearings for the side carrier bearings. Could someone find out what the o.d. of the side bearings are? I measured the width of the bearing bore to be approx. 0.75" and the mating carrier o. d. at approx. 1.0375". I also measured the side bearing cap to be 2.833" i. d. but do not trust that to be the actual bearing o. d. This information might be on the bearing itself. Thanks, Fred
