Firstoff, my apologies if this isn't the correct forum - wasn't sure if this
belongs in general tech or fullsize tech.

I recently purchased a posi (thanks again Keith!!!) out of a '66 Bonneville
that I intend to install into my '70 Bonneville convertible. Does anyone know
if replacement clutches and springs are available for these units? The one
I received appears to be in very nice condition, but I haven't disassembled
it yet to inspect the clutches. I'd rather have the parts on hand to replace
before I start disassembly. I've heard that parts for this family or rears
(hybrid 10-bolt?) are very hard to come by.

Any other gotchas I might need to know about when making this swap? I
intend to reuse the original 2.93 gear set, so I'm hopeful this will be an easy
open to posi swap. Going to replace the pinion seal while I'm there, but don't
anticipate any big issues there.

I just had the rear in my 70 Bonne Convertable rebuilt. I had purchased an Eaton Posi unit to replace my one legger. I used the original gears, but replaced all the seals, bearings and races. I too have heard that a lot of the parts are not available for those rears. Eaton was able to provide the posi unit, bearings, races and shims.
