## Discrepancy

(CAN) 2 CHAFED MARKS APPROX 1/16" DEEP, 3/8" APART & 1/2" LONG, MADE BY THE WIRES OF THE SEAT HOSE THAT IS ATTACHED TO THE CABIN HEATER SHROUD ON THE OUTLET SIDE. HEATER SHROUD IS NOT A TIGHT FIT TO THE MUFFLER & I HAVE IN THE PAST NOTED WEAR ON THE MUFFLER SUPPORT RINGS FOR THE SHROUD. THERE IS ROOM FOR THE SHROUD TO ROTATE UNTIL THE SEAT HOSE & CLAMP TOUCHES & WEARS THE AFT CROSS TUBE. AFT CROSS TUBE REPLACED.
