> Is the T-5 not concidered to be a "light weight" transmission?

Yes it's very light weight. But it depends on what you are gonna be doing
with it. it will last forever behind a 258 with small tires. I put my t5
from my 85 cj7 behind a built 304 with 4.56 gears and 36x12.5" tires and it
lasted about two weeks. It worked fine on the street and as soon as I hit
the mountains it exploded. I would upgrade - no CJ t5 is world class, AMC
was too cheap for that.

Another option for you would be a T176 that would bolt right up to your 258
and d300 and you could even use the same bell housing/clutch. The bell
housing would need some minor machine work (new holes drilled). The t176 is
a medium duty and was put behind v8s from the factory. It has been in mine
for 4 months and i have seen some pretty good trails with it.

I see all the sites list the AX15 as a medium duty, which is what I put in
my 81 cj, 258 and D 300.
