Bill,

I used the 1950 GMC 150 make/model selection to do my search in RockAuto instead of the Chevy 3600.

However, after much rechecking this morning of RockAuto (as well as a number of other web search's using the original part numbers in hopes of finding a "cross-over" to a tapered roller bearing) I must acknowledge defeat. I even tried to do a search using the "B45" listed dimensions and completely struck out. not me

From what i could find, there appears to be no such animal as a suitable "outer" front axle roller bearing for the 3/4ton GMC (or Chevy 3600) applications that i could locate. blush

My humblest apologies to "old soldier 50" (and anyone else) for any possible hope bubbles being burst or unintentional misleading info. dang

Thanks for the correction sir! thumbs_up
