Help finding a couple replacement T bolts for inder head stock

[bryan]

Short story I purchased a used Shopbot with indexer, I'm putting it all back together and spindle and table are are working great but now getting the indexer up to working speed and now I've notice that I'm missing two of the large T track bolt the tail and head stock are bolted to the tracks, I've been looking and do not see any on the web, anyone got feedback where to find two missing, or is this a case where it better to call Shopbot and get a couple replacements?

I've attached one of the remaining one that holding the tail stock but head stock is free floating.

Thanks, Bryan
