I don't believe there are any spacer sets in 5mm I.D., especially in aluminum. However, you may have to use some 5mm washers. Not sure if any of these will work for you:

No it needs to be 8mm long.

My local Tru-Value Hardware store has a bunch of specialty pieces in the aisle with all the screws and bolts. There are a ton of spacer options in there. From nylon, aluminum, or steel.

I might have to check out ours.
