Cracked see-thru plastic on instument cluster

[Ali]

When I had bought my '93 525i (about a 5 weeks back) the odometer (kms/miles) was not working, well I could see it very faintly at very high engine speeds but not otherwise, so I do as per one of threads regarding removal of the cluster without removing the steering wheel or unplugging the battery (no guys no airbag ) the 4 clips are out no problem, cluster comes out too with some twisting and turning. I decided I would first just change the bulbs before going on to the more complex capacitators, bulbs changed and I re-attach the clips wow everything works, putting it back in with the help of an over anxious friend we manage to get it in but not before cracking and breaking a portion of the transparent plastic (thru which we see everthing in the cluster). Guys plz tell me I can buy this seperately and I won't have to waste my now working cluster for it.
