The rear in my wagon (dana 44) is going to need rebuilt. While I'm at it I'm going to swap gear cases and put in 3.73 gears. I found a used 30 spline case with spider and side gears for a real good price. Is it possible to convert the 19 spline dana to 30 spline? I've been getting conflicting opinions.

I can't help, all I know is the trucks used a different axle than the 'birds. Turned out my bird had a truck rear under it, which explained the lousy welds on the perches. About the wagons and interchange I just don't remember after 20 years. But these guys will know, and probably have anything else you need. They're local to me and first rate.

Thanks. I give them a call. I was hoping someone with a Tbird or wagon had done it so I could get first hand knowledge.

T-bird and wagons are the same.

Yes. That I do know. I was hoping someone had done the 19 to 30 spline conversion.

why do you want thefiner spline? if the wheel patern is the isue possibly the truck axels could be modified.
