As do Pro-Ject and I think some Jelco arms, or theoretically any arm with a mounting distance in the 210 to 212mm region, maybe a bit longer depending on the way the arm mounts, though even arms which fit physically may present some issues regarding VTA. None of them are insurmountable but you need to be prepared to think about issues as they arise. I fitted a Pro-ject 9c to mine it works very well ... but I had to remove it's lift lower mech and use the built in Lenco Lift lower (which actually looks better and works fine), I had to get an insert made for the arm collar (the Lenco pillar/collar was a few mm wider), I had to drill a hole in the top plate to take the anti skate hoop and I am using an extra mat to raise the record surface (or I could have used a cartridge spacer).
With the right tools, extending the arm hole isn't too bad a job ... but you may still have VTA issues. A lot of people get round it by cutting the corner right off and mounting to the plinth. Personally though I think it spoils the look (and possibly compromises the stiffness of the top plate). It does depend to some extent how good a job is done on it though. I have seen people convert their L75s into GL88/99 alikes - but that does require some good metal working skills.
