mack axles swap from spoke to hub pilot

[Pigpen]

Wondering if anyone knows or has done this swap and where to start I guess... do I have to order from mack or will other models fit mack spindles? My rears are 38k mack axles if that helps, want to switch to hub piloted and run aluminum rims. Thanks in advance! Any info or opinions greatly appreciated!

I want to do same thing but mine is 44000 rears.

I did my 95 Mack, it had eaton rears and Mack front axle.    I was able to get the rears from a truck parts shop but the Mack front I had to get from Mack.  I couldn't find any at a wrecker.   Prices weren't that bad but I'm not sure what the

rear mack ones will cost.   In fact I can't remember what I paid for any of them now.   The bearings took some figuring out and a good old parts man came too my rescue as numbers changed a bit.

I jumped to 24.5 from 22.5 as well and now all my trucks and trailers have the same tire size which is what I wanted.
