Not having the best of days today. I just finished putting my 8.8
rear out of my 00' Mustang GT Vert. back together. I ordered Superior
Gear axles which arrived at 31 splines. Removing my axles I find a
rather large differance in the dia. at the c-clip end. 28 vs. 31
spline. No help from Summit, Superior is on vacation until monday and
I have a 1,000 mile trip soposedly going on starting Thursday.

My question, after all the ranting bs I just laid on you is... Are
there 2 different live axle rears that were installed in 2000? The
new axles came in at 30-1/2" long according to Summit they are 30-5/8"
long. I could have miss measured. The old ones are 30-11/16" long, of
courese the same goes for these. Old ones are approximately 3/16"
longer than the new ones. Do I have a 98' and older 8.8 rear under my
Mustang possibly? Just looking for possibilities, thanks for looking.
Tag on rear info as follows... It is definately a posi rear.

Stock is definitely 28 spline for 96-04. I believe there is a
difference in length between the 96-98's and 99-04's but I don't have
the specific measurements handy for the stock pieces. Here's a link
to Moser's application page, they list the measurements as 29 31/32
for the 96-98 and 30 11/16 for the 99-04 for their replacement units.
I'd bet Moser's numbers are accurate.

No matter how you slice it the 31-spline stuff that Summit sent you
isn't going to get you down the road.

Thanks, I was beginning to second guess myself for awhile yesterday.
Now it's time for me to get back on the phone with Summit to straiten
this mess out.
