[Chevelle-list] trans/rear end

[Ryan Langstraat]

Alright all you number guys.... I came across what I believe is a 4 Speed Saginaw Torque Tube Tail Shaft tranny.  Please tell me (1)if  I am right (2) what vehicle it was in.    Machined surface on side of tranny =  15N634042 Stamping on side of tranny =     GM  3925656       Also, on one side of the differential housing  =   3959038  NF On the other side =  GM 57     Any help you guys can give me would be great.  I have looked through all of my books but obviously not the right ones...   Thank you   Ryan
