Rear end help on 69 Electra

[Andrew Neff]

I just bought a 69 Electra 225 and the spider gears are busted. I need all the help I can get. I'm not sure which rear end I have and I can't seem to find out which one I have. Would anyone know by any chance? If so, where can I get replacement parts? My spider gears are busted. Dies anyone have a spool or mini spool, parts, or rear end that will work or what rear ends out of what cars will work? I found one out of a 69 Skylark for sale, but I don't think it's wide enough. Help, suggestions, anything will help. Thanks!

From another site, this is a good summary of your 9 3/8 rear - Buick only!
You may have to put out the "parts Wanted" post for a 69 replacement.


"It looks like there were 5 versions of 9 3/8 rearends, in 3 "generations", and nothing from one generation will interchange with another generation:

'66 Riv: One UCA and a panhard rod, L & R carrier brngs same
'66 Electra/Lesabre/Wildcat: 2 UCA and no panhard rod, L & R carrier brngs same

'67 to '70 Riv: One UCA and a panhard rod, L & R carrier brngs different
'67 to '70 E/L/W: 2 UCA and no panhard rod, L & R carrier brngs different

'71 to '73 ALL: 2 UCAs and no panhard rod, L & R carrier brngs different

The '70 rear end housing won't go into a '71 car, because the mounting ears for the control arms are in different places."
