OK, i've not received hardly ANY help/info at all with this? I know a few AMC listers have done it. Whats needed to swap a 68-69 B body rear into my 74 AMX? . And..what is the strength of the WEAK 741 casting? 68-69 B body is roughly 1" narrower than my stock rear end. I have a 391 489 case to install...looking for a 742/489 with 355 gears also. Thanks , JoeThanks for any help!! __________________________________ Do you Yahoo!? Check out the new Yahoo! Front Page. www.yahoo.com
