Yes, but can you buy a 6 pinion carrier for Ford C-6 gears?

This is a picture of one from the ACRE NL web site. Performance Automatic.
I am going to make you check the web site for the phone number as penance
for not seeing this Chris :-)

Ask for the one without the splines that has the retangular tabs that fit
in
the housing. The one shown has splines for a shaft.

The one shown is the forward planet set.  The 2.176 - 1 redrive uses the
REAR planet set.  Do you know if they make the rear set in a six pinion
version?  I haven't been able to find one.

I just called Performance Automatic and asked. You are right they don't make 
one for the REAR planet set. Using the front planet set would take power from 
the planet carrier and give a 2.86:1 (or 3:1?) PSRU ratio.  

Harvey at Performance Automatic did not think Ford made a 3 pinion version 
for the REAR planet set so of course one could not merely modify it for a SIX 
pinion version. Harvey declined to make one from scratch for me.

Back to the NC milling machine and hog it out for a 2.176:1 six pinion version.
John Moran might make some for us. How many people are interested in a six pinion
version for the 2.176:1 PSRU ratio?

BTW John, I can send you a stock Ford four planet set you can copy. 

As an alternative the front planet set, six pinion version from Performance Automatic 
could be chucked in a lath and the spline part cut out. Then the six pinion shaft
roll 
pins removed and the pinion shafts drilled slightly over size for six bolts.  Then 
six shoulder bolts could be used to locate it such as Ross appears to be doing now. 
The bolt holes need to be slightly over size to allow the planet carrier to self
align.
