Subject: Re: rear gears wanted

Armand ,

What gear set do you have now....I have 2.87 gears in my 78
Concord...with a early 90's T5 ...seems to work OK....although
I  think a little lower rear gear would be better.

Jim

my response to Jim;
"I have 2.87 gears in the model 20 now. The Javelin came from the factory
with them.
I found a very reasonable priced 2.73 twin grip differential from a Jeep.
Mostly I'm looking
for the 2.73 gears because I felt lucky just finding a twin grip
differential for 2.73 gears. If I could find a twin
grip for the 2.87s I would go that way. The last one on ebay I saw sold for
way over what
I thought was affordable. Especially when I can find a 2.73 setup for way
less than half of what the 2.87 will
bring. I think the 2.87 set up I have now works pretty good but like I
mentioned I have to shift out of first
gear almost as soon as I get the car rolling. I know a guy who has a 73 AMX
with a T5 and 3.54 twin grip. He
says first in his set up is just border line."







what gear is your carrier from?  the 2.73/2.56 gears have their own
carrier separate from the 2.86-up gears.

iirc 2.73s and 2.56s could be found on some late-'70s amc v8s.  they
can also be found, with torsen posis, in hummers.  amc20 3.07s and
3.31s can only be found in jeeps.

i still would like to know if the hummer 3.08 fits the regular hummer
2.73/2.56 torsen carrier or if it has its own carrier.

i am assuming you know that the hummer [h1], true to its amgeneral
roots, has amc20 differentials.

my response to Andrew;

"The twin grip carrier came with 2.73 gears on it. It was in a Jeep CJ."

"I don't know much about Hummers except there aren't any in the yards around
here.
So I think they are just as tough if not tougher to find."

" Andrew I will certainly let you know if I happen across finding which
gearsets fit in
which carriers, I think Randy Guynn or some one had something about this a
while ago."

"I had heard that the AMGeneral H1 had AMC 20 axles. I've never been close
enough to one
of them to see for sure. I do know a fella up north has one, I see him every
once in a while, I'll
look closer the next time I see it."

To these two guys and everyone, thanks for responding and look through your
stuff for a set of
2.73 gears, let me know if you want to part with them.
Armand
