727 bearing dimensions

I'm looking for dimensions for the output shaft bearing for my '72 727 TF. The bearing that was in the trans has about .001/.002" clearance between the tailshaft housing & the outer race & about the same between the output shaft & the inner race.It is a metric bearing,35 x 72 x 17. Is this the right bearing? It doesn't look like it spun in the bore or on the shaft. I don't know the history of this trans but it doesn't look like its ever been messed with,and the bearing itself is good,just concerned about the fit. Thanks! Rod
