Hi Mark and all, It should be a 1 3/4 diameter pinion, and the case number should end in "742". Check this link for more 8 3/4 information than you probably need!http://www.autohobbydigest.com/8_75.html 300ly, Don Verity Rhode Island 300's E,F,&G ----- Original Message ----- From: Mark Schueller <f41324@xxxxxxxxxxxxx> To: Chrysler 300 Club <Chrysler300@xxxxxxxxxxxxxxx> Sent: Wednesday, October 25, 2006 7:35 AM Subject: [Chrysler300] 300C Rear End > > Greetings All: > > Thanks to help from a number of club members, I now know that the carrier (pumpkin) in my rear axle is early '60s Mopar with a pinion shaft diameter of 1-3/8". Does any one know what the pinion shaft diameter of the 300C is or should be? Pinion shaft diameter (cross sectional area) indicates the strength of the unit. I don't know why any body would know this "off the cuff" but I thought I'd ask. :-) > > Thanks. > > Mark Schueller > 300C, 300F > > > [Non-text portions of this message have been removed] > > > > To send a message to this group, send an email to: > Chrysler300@xxxxxxxxxxxxxxx > > For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm > > For archives go to http://www.forwardlook.net/300-archive/ > Yahoo!
