1G 5spd vs Auto Front Axle shaft size

[er82]

Hello, I was under impression that for 1g the front axles are the same for 5spd and auto. However, I just checked the shaft diameters, and the 1990 5spd is 23mm and the reman axles from 1992 auto are 25mm. I only have one. So, are those the revised ones? Should I use the ones I have or find the larger one? They have round inner axle cups. Looks like the ebay ones. I intend to drag race eventually and hope to avoid broken axles.

Look at the 7th post down. I would go bigger, they probably changed them for a reason.

The other thread refers to fwd long driver side axle being swappped to awd axles.

Per this thread it looks like the aftermarket axles are beefier.

The axles are different on the AWD models but the 5 speed axles still work with the auto. I have been using 5 speed axles on both my auto 1g's with no problems. For informational purposes, 1 of my DSM started life as a manual and was converted to auto and the other was already an auto.

Are you sure the small one isn't a fwd axle?
