    Would this be the same as a Spicer N400?

    I can’t edit my last post but tye casting number on mine is 401OP102 and the used Spicer N400 carriers in seeing with Vander Haggs is 401CF102. It’s possible i misread it and mine is a CF not and OP since the OP number didn’t cross at all on a google search

    Upon further examination it is a 401CF102 Spicer rear end. Some of you may have know this but I did not. This makes me feel better since drop out carriers are under $800 for an N400 if worst comes to worst and I have to replace it. Hoping to tear into it some today and see what’s going on back there.
