What it is and where it goes
This is a hanger pair, not the flap itself. Two black steel arms, angled at 45 degrees, 27 inches long, drilled on 2-1/2" bolt spacing to match up with standard flap mounting patterns. Guys run these behind rear axles on trailers, straight trucks, and some dump bodies when they want the flap kicked out wider than a straight-drop hanger allows - usually for tire clearance or DOT spray requirements on wider stances.
Because it's a universal angled hanger and not something stamped to a specific chassis, fitment comes down to bolt spacing and arm length matching what's already on the truck or trailer, not a VIN-specific part number from the cab and chassis maker.
How the cross numbers line up
FD003, MFHA10B, and PN-3-C-005-BK all show up because they're the same basic angled hanger design - 27" length, 45-degree bend, 2-1/2" hole spacing - made by different manufacturers for the same aftermarket mud flap accessory slot. That's why they interchange: it's a generic mounting bracket, not something tied to a drivetrain or axle assembly.
Where guys get burned is bolt spacing and arm length. A 3" spacing hanger will not line up on a 2-1/2" pattern, and a shorter or longer arm changes how far out the flap sits and how close it gets to the tire. Before you order, pull the old hanger off and measure center-to-center on the bolt holes and the arm length end to end - don't just go by what looks similar hanging on the wall.

Frequently asked questions
Does PS-BD.01.UN.012 fit my straight truck?
Depends on the bolt spacing and arm length on your current hanger, not the truck make - this bracket is a universal angled mud flap hanger, not something tied to a specific chassis. Measure your existing hanger's bolt spacing and arm length, or give us the number off it, and we'll confirm before you order.
Is this the same as the Fortunes MFHA10B?
Same basic design - 27" angled arm, 2-1/2" bolt spacing - so it crosses over. Different manufacturer, different part number, but the mounting pattern and geometry match. If your old hanger is stamped MFHA10B, this should bolt in, but confirm the spacing on yours first since these arms get copied with slight variations.
Will this work with 3-inch bolt spacing flap hardware?
No. This hanger is drilled on 2-1/2" spacing. If your flap or existing hardware uses 3" spacing you'll need a different hanger or you'll be re-drilling holes, which we don't recommend on a load-bearing bracket. Measure before you order.
