will the spider gears from an open diff go into an IRS diff

my friend, reloader, and I are both thinking of doing the trac-lok diffs in our cars. I am just curious if the open diff spider gears will go into the trac-lok diff? I have not read on here any one saying to just swap out the spider gears from the open diff, but i thought I would double check and see if we could do that, He is changing the spider gears on an 04 cobra carrier and housing to make it a 28 spline. I will be changing the spider gears on a mustang 8.8 carrier to make it an irs carrier so it has the beveled edge pnt eh spider gears. Thank you again for your help.

I'm curious about this as well...

As it stands I have a spare Open T-bird pumpkin I would like to build up. I can grab a 8.8 solid axle trac-lok carrier from the shop. If I can pull the spider side gears out of the open diff and rebuild the 8.8 solid axle carrier with them, that would be great!

Thanks ahead of time...

Won't work. The spider gears for trac-lok have outer splines on the carrier side to hold the clutches in place. Opens are completely smooth

Those would be the side gears, with the splines for the steel plates in the clutch packs. But perhaps the "pinion" spider gears are the same?

I have heard the smaller gears called "pinion" gears, not to be confused with the other "pinion" gear in the differential.

Technically speaking the splined gears are side gears and the other two are spiders. I've never heard those referred to as pinion gears.

I saw them called that on the sheet that is included with a Ford spider gear kit.

"Differential pinion gear" and "limited-slip differential side gear"

so I guess the "pinion/spiders" are the same between open and traction lock units.

I just replaced my spider gears when I rebuilt the traction lock. Some of the smaller "pinion/spiders" were chipped.
