Hello all, I'm in need of a 1955 chevy 235 #2 main bearing. I believe it's also called the thrust bearing. Does anyone have a bearing set laying around at all? Or even just the single one. Either or.

Sealed Power Main Bearing Set 853M20 

(These are .020 undersize)

I've searched all of the internet and I have no luck whatsoever finding a set. Seems like they have become unobtainium.  My truck is on jackstands and been like this for 2 weeks with no end in sight.

If anyone could help me out it would be greatly, greatly appreciated. Either point me to a source that actually has them in stock or if you have a set.your willing to sell. Please let me know. 

Thank you
