Picked these up recently but they don't look correct for my later BX's - see picture... (I think these are probably for Mk 1 BX arms - I've seen similar ones in the early Haynes manual)
The part no - 95 494 717 seems to be replaced by the part number for the later slightly longer and metal encased bush that's used on the BX arms that I have...
I have 2 of these bushes and will sell for £10 each with free UK posting..
If I remember right you can check the diameter, I believe the early type had a 14mm pin through and the later ones a 16mm. Only done the later type which were a tenner the pair (Neat Autos), but those early ones must be very rare now. Early can be converted to late type though you need new pins....
