Tommy Bolin 40th Anniversary album box set. (missing 2 CD's)

My name is Al and I purchased this vinyl box set thru E&Brecords which is out of business. When I bought this collection, I was renting a bedroom (so no audio equipment), so album was packed away for about a year before I was able to open it and find out that disc's were missing, which during this time E&Brecords went belly up. I'm looking for any info as to how I might be able to retrieve or purchase these cd's. Sam at Elusivedisc.com suggested that I try the forums thru Audiogon. Any help would be greatly appreciated. Thanks
