used arb winch bar

ive just bought an old 60 with a winch bar thats about 20mm too narrow for the chassis rails.

who ever fitted it did a pretty rough job with spacers etc .

Would anyone be able to tell me what car this thing is sposed to be on ?

There's a small tab welded onto the passenger side of the rear of the bar with the number 3418010 on it , im thinking its a part number .

it looks like the right on compared to photo's but just narrower than the rails .
