Installing 800k/1.44mb Apple floppy drive

[Zhinu]

Does anyone know what drive carrier you need to install an Apple 800k/1.44mb drive into a Sun Remarketing Macintosh XL? I have one that has a third party drive (a modified Fujitsu with leaking SMD caps) that has begin to fail, and while I assume recapping it will fix it, I'm wondering what would be the best way to replace the drive if it fails in the future?

So far I've found that if you remove/bend pin 9 on a 1.44mb floppy and toss it into a machine that has the 800k ROM/IWM (speaking of that, is the IWM shared with any other Macs?) it works as a 800k drive without any modifications needed to the Lisa. However, with my current drive mounts, the floppy drive sits too high, and gets blocked by the bezel.

The IWM used on the 2/10 I/O Board is the "A" variety, which is specified on the Apple ][ IWM disk controller schematic, but I suspect not many of those were produced. The first Macintosh varieties used the "B" version, which I believe is a suitable replacement, but still not readily available.

It seems possible that someday, the creator of the IWMLess will produce a substitute for the IWM that will work in the 2/10.

The 800K drive upgrade was developed by Sun Remarketing, so the bracket to hold the drive was not a mass produced Apple part. Various 800K drives were sold by SR (eg. I have a "Chinon" drive), and I suspect not all of the drives need the same bracket. At the least, there were multiple manufacturing runs of brackets and not all of the brackets are the same. I believe DaFax also had some brackets made. VintageMicros had some for a while, but at this point, I think you may need to adapt what you have or perhaps there is a 3D-Printable model somewhere.
