Oh, I didn't mean cutting existing axles. I was trying to tell the OP
that shafts are not manufactured (cut/rolled splines, forged,
induction/thru hardened, whatever) for maximum torsional strength in one
rotational direction at the expense of the other. That is, if he puts
two RH shafts in his custom D44 housing, the one on the left will be
just as strong as the right when pulling in the forward direction.
Correct, yes?

Nice dragster. Did you do your own re-splining?

At 3" lift you might risk punching the stock slip yoke home on the tcase
tail shaft when you switch to a D44. With my swapped-in D44, 4.5" lift,
longer rear spring shackles, and stock rear shaft, the slip yoke stops
just short of hitting home in the tcase when the distance to the pinion
is at the minimum. Be sure to test/calculate the excess slip space
through your full range of rear suspension travel.

Hi Steve,
Dragmaster, Oceanside, California re-splined them in 1959.
Talking about switching axle sides, which I don't have a problem
with, reminds me we used to paint a line down them, and they would make
up to six twists before they let go on this '27 T we had switched from a
successful D/Altered flathead to a Hemi in 1958:

replace it with a ford 8.8 which also has disk brakes.
cheap and stronger than a 44.
almost a bolt in fix.
