Front lower wishbone arms

[mach2andy]

I've just split my front suspension components prior to sending them for plating. The LH & RH front lower wishbone arms look identical, and are marked with the same number 1L05154. But the SNGB catalogue gives different part numbers for these 2 items as though they are handed. Can anyone explain this?
The upper wishbones are definitely handed and carry different part numbers 1L05156 & 1L05157 and the rear lower wishbone arms have the same number 1L05131 and look identical.

Yes Andy....the front part of the lower wishbone has a cutout where the torsion bar slots in....hold the two together and you should see it... if you look here....you will see right on the end where the torsion bar fits it has a reduced thickness . Steve

Thanks Steve
Yup got it now. Couldn't see for looking. Maybe that [rather misleading] number on the arm is the basic casting number before the item goes to be machined? Just a guess? Having just seen the price of these suspension components, I'm very glad that mine are all in good shape. Phew!!
