Seems that the air dryer for the M1081 is mounted different from the standard LMTV. The threads here show the old and new filters mounting directly to the frame. The old finned filter is removed and the new one mounted using a notched universal mounting plate. Reuse the original hoses only adding a bushing to the pressure sensing line.
Not so for my 1997 M1081. The dryer is mounted on a bracket that is at 90 degrees to the frame. The bracket is attached to the frame with the much maligned Huck bolts and is covered with tan paint, which leads me to believe its original.
The new dryer mounts to the bracket perfectly without modifications. However, all lines must be modified. The input line fitting into the dryer is now against the frame and the fitting must point straight down for a new lengthened braided line. About 15” line and a 90 degree fitting to reduce the bend radius. The output line loops up and back down to the bottom of the new dryer using 2’ of line for enough curve. The sensing line must be extended about one foot and use a bushing or new fitting for the larger hole on the new dryer.
But it fits and works, making a quieter and slightly protracted hiss when relieving pressure.
Old dryer removed, it bolts on and covers the circular hole beside the battery box lid, four green dots where the bracket didn’t get painted. Pic shows the bracket and old hoses:

New dryer in place with new lines:

Lot note: the line from the compressor to the dryer must be braided with Teflon interior, flare fittings. The heat from the compressed air would otherwise melt normal nylon lines. So I was told...
