That would annoy me, ok you didn't specify a part number but you did go by a picture in his webshop. I know that sellers have the right to substitute items if it's in their terms and conditions but if you had ordered these & had already done the work for this style to fit or were replacing existing units the new ones he has sent wouldn't fit.
I got caught out with some electronic components I bought from RS in a similar way, my fault I suppose for not reading the technical spec properly but not being a whizz with electronics I just went by the picture. RS were very quick to point that out to me so won't order from them again if I'm not 100% sure exactly what I need, what it looks like & how to use it properly lol.
i can imagine what has happened here though

So, I emailed chai, saying il have four of those ball nut housings to suite 1610 rails.

assuming he would send me the ones on his ebay shop er... these
so creaky has noticed chai has ball nut housings in his ebay shop.. but then instead of going through the shop has contacted him direct and asked for 4 ball nut housings... yes maybe chai should have maybe said i have a few different types and asked which ones..

chai has likely just sent out the most popular ones. luckily though this worked out well any way
