There was a long discussion some time ago about he rear end ratios. Seems that they will fit from 1941 through 1955, there is a wide range of gear ratios from these years.<P>Good luck<P>Jim Schilf / palbuick@aol.com

The gears themselves will fit thru 1953. 1954-55 are different, but then you can swap the whole 54-55 third member to an earlier axle housing. Try any of the Buick-specialized boneyards listed on my links page, <A HREF="http://www.nic.fi/~marlin/buicklinks.htm" TARGET=_blank>www.nic.fi/~marlin/buicklinks.htm</A>

Try Wheatbelt(ad in the Bugle) Your best bet is to take the assembly out of the front of the housing as a unit.Ken is very knowlegable on Buick parts.

I have a complete 55 rearend & torque tube in good shape if that will swap ? <BR>unclepete@foxinternet.net

Thanks for all the posts everybody, I just ordered a 3.60 gear set from Wheatbelt, and will let you all know what happens when I try to install it, wish me luck! M. Burnett
