Mounting new hardware in vintage hardware

[Jim Leonard]

I finally got a chance to try the Silicon Valley Computer ADP50L (an 
8-bit ISA IDE controller) in my IBM 5160 and I have to say, I love the 
thing and want to put it to full active use.  My problem is, how do I 
properly mount a "modern" (3.5" half-height) hard drive into the case?

Looking at the existing ST-225 that's currently in there, it has much 
larger dimensions so that it not only reaches the screw holes on the 
side of the case, but for additional stability has the front faceplate 
directly screwed onto it as well.  It's in there pretty tight.  I can 
remove it, but how do I put my 340MB smaller drive in it's place?

I know I could just lay it down gingerly and try not to move the case, 
but I've got kids and wouldn't want an accident to damage the drive (or 
worse, damage the innards if the drive goes flying into the center of 
the machine).

Any ideas?  Is there a safe, non-flammable, non-disintegrating material 
I can use to wedge it in perhaps? (ick)
