Here's my score from the recent Charlotte Autofair swapmeet. I plan to use it on my '34 5 window project. I've got a 301 Chevy engine, Borg Warner T10, & '59 Pontiac rearend. I want my car to appear to have been built during the early/mid 60's. The unusual thing about this bell housing is that it is embossed with text "55 TO 61 CORV - PASS". Because the other versions of this item that I've seen has the text "55 TO 62", rather than "TO 61" like mine, I assume mine was made in 1961 - prior to the introduction of the 1962 Chevrolets. I'm curious about the style of dust shield originally used with these units. Were they just sheet metal that covered the opening below the engine block, or were they a full cover plate that protected the back of the block - kinda like the modern Lakewood units? Does anyone have photos or information on this vintage piece? Thanks, guys.
