Last December I bought one of Stumpy's stands for my FE with an Aviaid pan. Fits perfectly and excellent workmanship. He calls it part# "FE-W" and fits all the wider "T-pans". It was $52.
I like it because it only uses the block's side mounts and left the back clear to mount and dial-in the bellhousing.
His real name is Kurt Stumpf, and you can reach him at
