In plugging away at my Dana 30 to 44 conversion I have cleaned up the parts from the various axles I've gathered. The Dana 30 has six hole spindles, will those 30 spindles work on the drum brake 44 that I'm putting together? Also the hubs off the old 30 are the cleanest ones I have. Can I use those on the 44 spindles if I had to, or are the 30 hubs different than the 44 hubs? Thanks for the input!
