Dutchman has a housing end. My 9" Ford has 6x139.whatever bolt pattern with stock Silverado brakes. Even the stock E-Brake.
I am running a ball bearing but it can run the Timken set 20 Tapered roller too. I am using their axles.
The E-Brake is important to me. Spit the driveshaft or trans out on the ground on an incline.... You can't get out of the truck.

Well it's not completely finished, have to still figure out pinion angle and weld out spring perches, also if I'm going with an over or under axle anti-roll bar.

Might not be the 1st 14 bolt with 9" ends but it might be the 1st with a spool based on my adventure. On a last ditch effort search I came across a company that machines various fancy sled pulling parts and just so happened to make a couple different spools (like AAM 11.5, Dana 80, Sterling 10.5). Sent them some preliminary dimensions of my carrier and it just so happened to fit into their mold blank. So sent them my carrier to finalize and the rest was history (well 8 weeks later).

Long story short there is a 14 bolt 9.5" spool in existence and fit was damn near perfect, had to take .025 out of one of the OEM shims but gear pattern was about the best the fella who set it up has ever done. I also had them set it up for 35 spline in lieu of 33 because it just makes sense with blank canvas.
