Square end cap brush rolls and two speed switches....
It's hard to find either of those items. I just bought a vibra groomer I off of ebay. It was rather pricey, but works well in the 260. As for the switches, old vac shops may have used or nos, I bought a couple of them a few years back when they were still available, but used both ot them when I refurbished the two I have. The only other way to get one would be to find a 260 for parts....or an older vac shop with nos.
I went back to the Vac Sew Center where I bought these and they were still listed on their website and ordered a couple more, but they emailed me a few weeks later saying they were no longer available......Brush roll will be easier to find although with the square ends, that is getting harder also. You might be able to find the square ends to fit a vibra groomer I or II and just replace the end caps. See ebay auction # 160691010555, but it is $95.00.......
