shouldn't be hard to find a place to make you one. Any Race Fab/Suspension (eg Leda Suspension) or Metal Fab workshop will be able to do it, but it will probably set you back at least $200 I reckon. + chroming - whatever that costs. be prepared for them to snigger when you mention that

Or if you are prepared to do it (or even just arrange it) yourself you could do it for less than $50...
I had the strut plates made to my measurements by a Metal Fab shop - water cut from 3mm plate ($30), then I bought a peice of thick wall tube ($6), which I cut to length, put a slight bend in to clear engine, ground the ends flat and welded to the strut plates ($0 - mate with welder). Then it's just a can of paint ($8 if you don't have one lying around) and your done.
